Converting Rear Drum Brakes to Disc Brakes for Enhanced Performance and Safety

Converting Rear Drum Brakes to Disc Brakes An Overview

When it comes to vehicle performance and safety, brake systems play a critical role. Many older vehicles come equipped with rear drum brakes, which, while adequate for most driving conditions, can fall short in terms of performance, especially under heavy braking or in demanding driving scenarios. As a result, many enthusiasts and everyday drivers alike consider converting from rear drum brakes to disc brakes. This article will explore the benefits of such a conversion, the process involved, and important considerations.

Understanding Brake Systems

Before diving into the conversion process, it's essential to understand the fundamental differences between drum and disc brakes. Drum brakes consist of a cylindrical drum that rotates with the wheel, while brake shoes press outward against the drum when the brakes are applied. In contrast, disc brakes employ a rotatable disc that is squeezed between two brake pads, providing superior stopping power and heat dissipation. This fundamental design difference leads to various performance attributes that can significantly affect your vehicle’s handling and safety.

Benefits of Converting to Disc Brakes

1. Enhanced Stopping Power Disc brakes generally offer better stopping performance than drum brakes due to their ability to dissipate heat more effectively. This is crucial in preventing brake fade during heavy braking situations, such as towing or hilly driving.

2. Faster Heat Dissipation Disc brakes tend to run cooler than drum brakes, which can prolong the lifespan of the brake components and improve overall brake performance, especially during spirited driving or performance applications.

3. Improved Maintenance Disc brakes are often easier to service than drum brakes. Brake pads can be replaced without removing the entire wheel assembly, and inspecting disc brakes is generally more straightforward than checking drum brakes.

4. Better Response Times The design of disc brakes means they respond faster to braking inputs, offering improved vehicle control and safer handling when quick stops are necessary.

5. Cosmetic Appeal Disc brakes often have a more modern aesthetic, which can enhance the appearance of your vehicle, especially for show cars or restorations.

Converting from rear drum brakes to disc brakes requires careful planning and execution. Here’s a simplified overview of the process

1. Select the Right Kit Various aftermarket companies offer conversion kits designed specifically for numerous vehicle models. Select a kit that is compatible with your vehicle and meets your performance needs.

2. Gather Necessary Tools A successful conversion will require standard tools like wrenches, a jack, and potentially specialized tools for brake assembly.

3. Remove Old Components Begin by raising the vehicle and securely placing it on jack stands. Remove the wheels and then the existing drum brake system, including the drum, shoes, and hardware.

4. Install New Disc Components Follow the instructions provided with your conversion kit to install the new rotor, caliper, and associated components. Ensure everything is tightened to the manufacturer’s specifications.

5. Bleed the Brake System Once the installation is complete, bleed the brake system to remove any air bubbles, ensuring optimal brake performance.

6. Test Drive After the installation, perform a test drive to ensure the new braking system works correctly. This will help identify any issues before they become critical.

Important Considerations

While the conversion offers numerous benefits, it is essential to consider a few factors. First, ensure that your vehicle's wheel and suspension system can accommodate the new components. Additionally, understand that changes in the braking system may require corresponding adjustments to other areas of the vehicle, such as the master cylinder.

Conclusion

Converting rear drum brakes to disc brakes can significantly enhance your vehicle's safety and performance. While the process involves a significant investment of time and resources, the benefits of improved stopping power, better maintenance, and enhanced aesthetic appeal make this upgrade worthwhile for many drivers. Whether you are looking for better performance in everyday driving or seeking to improve your vehicle for motorsport applications, moving to a disc brake system is a proven upgrade that can deliver exceptional results.
