Converting the front drum brakes on a specific series of classic Chrysler vehicles to a more modern disc brake system is a common modification. This system enhancement involves replacing the original drum brake components with rotors, calipers, and associated hardware designed to provide improved stopping power. This modification specifically targets vehicles built on Chrysler’s “A-body” platform, such as the Plymouth Valiant, Duster, and Dodge Dart.
The motivation behind this upgrade stems from the inherent advantages of disc brakes over drum brakes. Disc brakes generally offer superior stopping performance, reduced brake fade under repeated use, and better overall control. Historically, drum brakes were standard on many vehicles, but the improved safety and performance characteristics of disc brakes have made them a popular aftermarket modification for those seeking to enhance the driving experience and safety of these classic cars. This type of modification can enhance the resale value and also attract classic car collectors and car enthusiasts.
The subsequent sections will provide a deeper dive into the specific components required for such a conversion, outlining the typical installation procedures and highlighting potential considerations when embarking on this project.
1. Spindles
The journey of a Mopar A-body towards disc brakes invariably encounters the spindle. It stands as the foundational component, the very cornerstone upon which the entire conversion rests. Without the correct spindle, the calipers, rotors, and all their associated hardware find no secure home. It is the silent enabler of superior stopping power.
-
Mounting Platform
The spindle acts as the primary mounting point for the disc brake caliper. Its design directly dictates whether the chosen caliper can be properly and safely secured. Original A-body drum brake spindles lack the necessary provisions for caliper attachment, rendering a conversion impossible without either replacing or heavily modifying them. Selecting the correct spindle that is designed to accept the caliper mounting points is critical for safety. An incorrect choice can lead to catastrophic brake failure.
-
Bearing Compatibility
The spindle also houses the wheel bearings, essential for smooth and safe wheel rotation. Disc brake conversions often require larger or different bearing configurations than those used with drum brakes. The spindle must, therefore, be compatible with the specific bearing set required by the new rotor. Failure to ensure this compatibility can result in premature bearing failure, wheel wobble, and potentially dangerous driving conditions.
-
Steering Geometry
Altering the spindle can influence the vehicle’s steering geometry, including parameters like scrub radius and camber. A poorly chosen spindle can negatively impact handling characteristics, potentially leading to increased steering effort, uneven tire wear, or instability, especially under braking. Correct spindle selection maintains the intended steering dynamics, ensuring a predictable and safe driving experience.
-
Structural Integrity
Given its role in both braking and steering, the spindle must possess sufficient structural integrity to withstand the increased forces associated with disc brakes. Inferior or damaged spindles can flex or even fracture under heavy braking, leading to complete brake failure and loss of control. Inspection of existing spindles, or selection of high-quality replacement parts, is paramount to ensure long-term safety and reliability.
The spindle, often overlooked in the enthusiasm for shiny new rotors and calipers, emerges as the unsung hero of the A-body disc brake conversion. It is the keystone to safety and performance, a component demanding meticulous selection and installation. Without a solid foundation at the spindle, the dream of enhanced braking becomes a potential nightmare.
2. Calipers
In the transformation of a Mopar A-body’s braking system, the caliper emerges not merely as a component, but as the active hand gripping the rotor, the translator of hydraulic pressure into immediate stopping force. It is the heart of the disc brake system, converting potential energy into kinetic control.
-
Hydraulic Actuation
The caliper’s primary function is to house pistons that, when pressurized with brake fluid, clamp brake pads against the rotor’s surface. This clamping action generates friction, slowing the rotation of the wheel. In the context of a Mopar A-body conversion, the choice of caliper directly impacts the available clamping force, influencing stopping distances and overall braking effectiveness. A single-piston caliper, while simpler, might prove insufficient for demanding driving conditions, whereas a multi-piston design offers increased force distribution and modulation.
-
Heat Dissipation
Braking generates significant heat, and the caliper plays a role in dissipating this thermal energy. Caliper design, materials, and even color can affect its ability to shed heat efficiently. During a disc brake swap, especially on a classic vehicle like an A-body, selecting calipers designed for effective heat management prevents brake fade, a phenomenon where braking performance diminishes as temperatures rise. Brake fade leads to dangerous situations, compromising safety on long descents or during spirited driving. Vented rotors can improve heat dissipation, but calipers remain integral in managing this crucial aspect.
-
Mounting and Compatibility
The caliper’s mounting points must precisely align with the spindle’s mounting provisions. Compatibility ensures proper fitment and safe operation. The caliper choice directly affects the spindle selection. Original A-body spindles designed for drum brakes do not have the necessary caliper mounting points, necessitating either spindle replacement or modification. Ensuring correct caliper and spindle compatibility is paramount to prevent component failure and maintain safe vehicle operation.
-
Brake Pad Selection
The caliper design dictates the type and size of brake pads that can be used. Different pad compounds offer varying levels of friction, wear resistance, and noise characteristics. A disc brake upgrade can broaden the range of available pad options, allowing for a tailored braking experience. For example, performance-oriented pads enhance stopping power, whereas ceramic pads offer quieter operation and reduced brake dust. The caliper is intrinsically linked to the brake pad performance, influencing the overall feel and effectiveness of the braking system.
The caliper, therefore, represents a crucial decision point in the enhancement of a Mopar A-body’s braking capabilities. Its performance characteristics and compatibility determine the effectiveness and safety of the entire system. Careful consideration of these factors guarantees a transformed driving experience, turning a classic into a safer, more controllable machine.
3. Rotors
The tale of converting a Mopar A-body to disc brakes is, in many respects, the story of the rotor. It is the protagonist, the surface against which the drama of deceleration unfolds. Where drum brakes once hid their workings within a dark, enclosed chamber, the rotor stands exposed, a testament to the raw physics of stopping power.
-
Surface Friction and Deceleration
The rotor’s primary duty is to provide a consistent, predictable surface for the brake pads to grip. The very nature of its material composition, its surface finish, and its overall diameter dictate the amount of friction that can be generated. A larger rotor offers a greater area for this interaction, translating directly into increased stopping force. Imagine a Valiant, hurtling down the road; the rotor is the critical link between momentum and control. The degree of friction it provides is the difference between a controlled stop and a near miss.
-
Heat Management
Friction is a double-edged sword. While essential for slowing down, it inevitably produces heat. Rotors must effectively dissipate this thermal energy to prevent brake fade, a phenomenon where braking performance diminishes drastically. Vented rotors, with their internal cooling channels, are designed to combat this. Consider a Duster descending a long, winding mountain road. Repeated braking can cause drum brakes to overheat rapidly, leading to a loss of stopping power. Disc brake conversions with properly sized and vented rotors significantly mitigate this risk, maintaining consistent braking performance even under demanding conditions.
-
Material Composition and Longevity
The rotor’s material dictates not only its frictional properties but also its durability and resistance to wear. Rotors made from high-quality cast iron, for instance, offer a good balance of performance and longevity. However, prolonged use can lead to scoring, warping, or cracking. A Dart, meticulously maintained for decades, may still be running on its original drum brakes, but a disc brake conversion with modern rotors offers a degree of reliability and safety that the original system simply cannot match. Regular inspection and timely replacement of rotors are crucial for maintaining optimal braking performance.
-
Compatibility and Fitment
The rotor’s dimensions, bolt pattern, and offset must be perfectly compatible with the chosen spindle, calipers, and wheel configuration. An improperly sized or incompatible rotor can lead to dangerous rubbing, uneven brake pad wear, or even complete brake failure. Visualize an enthusiast attempting to install a disc brake conversion kit on their Barracuda. If the rotors do not properly fit the spindle or interfere with the wheel, the entire project grinds to a halt. Ensuring precise compatibility is not merely a matter of convenience; it is a matter of safety.
Thus, the rotor’s role in a Mopar A-body disc brake conversion extends far beyond being a simple disc. It is a nexus of friction, heat, material science, and precise engineering. The careful selection, installation, and maintenance of rotors are paramount to realizing the full potential of a disc brake system, transforming a classic Mopar into a safer, more capable machine.
4. Master Cylinder
The implementation of a front disc brake system on a classic Mopar A-body necessitates a critical evaluation of the master cylinder. The original drum brake master cylinder, designed to operate a system with different hydraulic requirements, may prove inadequate for the new disc setup. This is not merely a matter of bolting on new components; it’s a fundamental shift in the way the braking system functions. A drum brake system typically requires lower hydraulic pressure and volume compared to a disc brake system. When the original master cylinder is retained, insufficient pressure and volume can result in a spongy brake pedal feel and diminished stopping power.
Consider the case of a meticulously restored Plymouth Duster, its original drum brakes replaced with a gleaming new disc setup. The owner, eager to experience the improved stopping power, neglects to upgrade the master cylinder. The result is a disappointing brake pedal feel, requiring excessive force to achieve even moderate deceleration. In emergency braking situations, the consequences could be catastrophic. A more suitable master cylinder, designed to deliver the increased pressure and fluid volume required by the disc brakes, would provide a firmer pedal and dramatically improved stopping performance. Often, a master cylinder designed for a later-model Mopar with factory disc brakes is a direct bolt-in solution, representing a relatively simple but essential upgrade.
The relationship between the master cylinder and the disc brake conversion is thus one of cause and effect. The new brakes require more hydraulic power; the original master cylinder may not deliver it. This mismatch can compromise safety and negate the benefits of the conversion. Careful consideration must be given to matching the master cylinder’s specifications to the requirements of the new disc brake system, ensuring a reliable and effective braking solution. This often means opting for a larger bore master cylinder or one specifically designed for disc brake applications.
5. Brake Lines
The upgrade to front disc brakes on a classic Mopar A-body presents more than just bolting on new hardware. It is a careful orchestration of interconnected components, each playing a vital role. Among these, the brake lines, often overlooked, are the arteries of the system, carrying the lifeblood that translates foot pressure into stopping power. A poorly chosen or neglected brake line can cripple the entire effort, rendering even the most sophisticated calipers and rotors useless. The original rubber lines, often aged and deteriorated, are simply inadequate for the increased demands of a disc brake system. The increased pressures of a disc brake system will quickly find the weak points of the rubber lines.
Consider a Dodge Dart, carefully restored and now sporting a new disc brake conversion. The owner, in a rush to complete the project, reuses the original, decades-old rubber brake lines. Upon the first hard braking, one of the lines bursts, spewing brake fluid and leaving the driver with a useless brake pedal. The improved stopping power of the discs becomes irrelevant; the car is effectively without brakes. Stainless steel braided brake lines are a common and wise choice as these offer an additional layer of protection and also do not expand or flex like the old rubber lines.
The selection and installation of brake lines, therefore, are not mere afterthoughts but critical steps in a successful disc brake conversion. Stainless steel braided lines, offering superior strength and resistance to expansion, are a wise investment. Correctly sized and properly routed lines, free from kinks or chafing, ensure reliable and consistent braking performance. The integrity of the brake lines is the foundation upon which the entire system rests, translating pedal pressure into life-saving stopping force. Ignoring them is akin to building a house on sand; the inevitable failure will be both costly and potentially dangerous.
6. Proportioning Valve
The saga of a Mopar A-body converted to front disc brakes finds its most subtle, yet critical, chapter in the selection and installation of the proportioning valve. While gleaming calipers and slotted rotors capture the eye, this unassuming component quietly orchestrates the balance of braking force, preventing the transformation from becoming a dangerous imbalance.
-
Balancing Act
The proportioning valve is a hydraulic regulator. It limits the pressure to the rear brakes, preventing premature rear wheel lockup. A Mopar A-body, originally designed with drum brakes on all four corners, typically lacks this valve. With the significant increase in front braking power from the disc conversion, the rear drums become prone to locking up under hard braking. This can lead to a loss of control, especially in wet or slippery conditions. The proportioning valve restores harmony to the system, ensuring that the front brakes do the majority of the work, while the rear brakes provide stable, controlled deceleration. The owner of a ’68 Barracuda, fresh from a disc brake upgrade, learns this lesson the hard way when the rear wheels lock up unexpectedly during a rainstorm, sending the car into a spin. A properly installed proportioning valve would have prevented this near-disaster.
-
Adjustability and Fine-Tuning
Some proportioning valves are adjustable, allowing for precise calibration of the front-to-rear brake bias. This is especially valuable for Mopar A-bodies with modified suspensions, different tire sizes, or specific performance goals. The adjustable valve allows the brake bias to be dialed in for optimal stopping performance and handling. Imagine a dedicated autocross enthusiast with a highly modified Dodge Dart. The adjustable proportioning valve becomes an indispensable tool, enabling the driver to fine-tune the braking system for maximum control on the track. Minute adjustments can shave precious seconds off lap times.
-
Combination Valves
Many aftermarket proportioning valves are actually combination valves. These perform multiple functions, including proportioning, metering, and brake failure warning. The metering function holds off pressure to the front disc brakes until the rear drum brakes have overcome their spring tension, ensuring a more even initial braking feel. The brake failure warning alerts the driver to a hydraulic leak in either the front or rear brake circuit. These combination valves provide a comprehensive solution for Mopar A-body disc brake conversions, offering enhanced safety and convenience. A meticulous mechanic, performing a disc brake conversion on a ’70 Plymouth Duster, appreciates the integrated functionality of a combination valve, streamlining the installation process and enhancing the overall reliability of the braking system.
-
Installation Considerations
The proportioning valve must be installed in the correct location within the brake system, typically in the line running to the rear brakes. Incorrect installation can render the valve ineffective or even cause complete brake failure. The valve must also be properly plumbed and bled to ensure proper operation. A novice restorer, attempting a disc brake conversion on a ’69 Dodge Charger, struggles with the installation of the proportioning valve, connecting the lines incorrectly and creating a dangerous situation. Proper research and attention to detail are essential for a successful and safe installation.
The proportioning valve, therefore, is not merely an accessory but a fundamental component in the conversion to front disc brakes on a Mopar A-body. It is the unsung hero, quietly ensuring that the newfound stopping power is harnessed safely and effectively, preventing imbalance and maintaining control. Its proper selection, installation, and adjustment are the keys to unlocking the full potential of the disc brake upgrade, transforming a classic into a safer, more capable machine.
7. Dust Shields
The narrative of a Mopar A-body’s transformation to front disc brakes often relegates dust shields to a minor role, a mere footnote in the larger story of calipers, rotors, and master cylinders. However, overlooking these unassuming components is akin to neglecting the foundation of a building; the structure may appear sound initially, but its long-term integrity is inevitably compromised. Dust shields, in the context of a disc brake conversion, serve as guardians, protecting the vital braking surfaces from the relentless assault of road debris, water, and grime. Their absence invites premature wear, diminished performance, and potentially catastrophic failure. The original drum brake systems on these classic Mopars were somewhat shielded by their enclosed design, but disc brakes present an exposed and vulnerable target.
Consider a valiant owner who meticulously upgrades their braking system, installing top-of-the-line calipers and rotors. Enthralled by the immediate improvement in stopping power, they dismiss the need for dust shields, viewing them as unnecessary frills. Over time, however, the exposed rotors become pitted and scored by road debris. Rainwater, combined with brake dust, forms a corrosive slurry that accelerates wear on the brake pads. The once-impressive braking performance deteriorates rapidly. Eventually, the rotors require replacement far sooner than anticipated, and the calipers suffer damage from the abrasive contaminants. This avoidable scenario underscores the crucial role of dust shields in preserving the longevity and effectiveness of the disc brake conversion. While not directly contributing to the brake system’s power, they ensure the system’s integrity and lifespan.
Therefore, in the broader tale of upgrading a Mopar A-body to front disc brakes, the dust shields emerge not as mere accessories but as essential protectors. They are the silent sentinels, guarding against the elements and ensuring that the investment in enhanced braking performance yields lasting returns. Their presence is a testament to foresight and a commitment to preserving the integrity of a classic machine. Neglecting them, however, invites a future of premature wear, diminished performance, and potentially dangerous consequences, a fate no enthusiast desires for their beloved Mopar.
8. Wheel Bearings

This conversion, however, demands more than just bolting on new hardware. It necessitates a holistic consideration of all interconnected components, with wheel bearings occupying a crucial, often understated, position. These bearings, nestled within the hub, facilitate the smooth rotation of the wheel, a seemingly simple task that becomes infinitely more critical under the increased demands of disc braking. The forces generated by deceleration, now concentrated at the front wheels, place additional stress on the bearings, demanding that they be in optimal condition.
Imagine a meticulously restored Plymouth Valiant, its original drum brakes replaced with a gleaming new disc setup. The owner, focused on the calipers and rotors, overlooks the condition of the existing wheel bearings. Months later, a subtle but persistent hum emanates from the front end, gradually escalating into a worrisome roar. The wheel bearings, weakened by age and the increased load from the disc brakes, are failing. The smooth, effortless rotation of the wheels is compromised, leading to uneven tire wear, reduced fuel efficiency, and, ultimately, a potentially catastrophic wheel failure. This scenario underscores the importance of either inspecting and repacking the original bearings or, preferably, replacing them with new, high-quality units during the conversion. The wheel bearings must be correctly sized and installed for the spindle as well as lubricated properly.
In conclusion, the wheel bearings, while often unseen, are integral to a successful Mopar A-body disc brake conversion. They are the silent partners, bearing the brunt of the increased braking forces and ensuring smooth, reliable operation. Their neglect invites a cascade of problems, from irritating noises to potentially life-threatening failures. Therefore, a conscientious approach to a disc brake conversion necessitates a thorough evaluation and, if necessary, replacement of the wheel bearings, securing not only improved stopping power but also long-term safety and peace of mind. The task also helps maintain the value of a classic car.
9. Installation Hardware
