How to Convert Rear Drum Brakes to Disc Brakes

Converting rear drum brakes to disc brakes is a popular modification that enhances braking performance and offers numerous advantages. While drum brakes are effective, they can suffer from issues such as heat buildup, reduced stopping power, and inconsistent performance under heavy loads. On the other hand, disc brakes provide better heat dissipation, more consistent performance, and improved overall safety. Here’s a step-by-step guide on how to convert rear drum brakes to disc brakes.

Step 1 Gather Necessary Tools and Parts

Before starting the conversion, ensure you have all the necessary tools and parts. You will need disc brake conversion kits, which often include new calipers, rotors, mounting brackets, and sometimes new brake lines. Additionally, you’ll need basic hand tools such as wrenches, sockets, and a jack.

Step 2 Safety First

Before you begin, make sure the vehicle is parked on a flat surface. Engage the parking brake and use wheel chocks to prevent any movement. Raise the rear of the vehicle with a jack and secure it on jack stands for safety.

Step 3 Remove the Drum Brakes

Start by removing the rear wheels and then the brake drum assembly. Disconnect the brake lines and remove the backing plate, keeping in mind the order of components for easier reassembly of the new system. Be cautious of any springs or clips that may pop off during disassembly.

Once the drum setup is removed, it’s time to install the new disc brake components. Begin by attaching the new mounting brackets for the calipers to the rear axle housing. Following the kit's instructions, install the new disc rotors on the axles. Make sure everything is secured tightly.

Step 5 Mount the Calipers

With the rotors in place, install the brake calipers over the rotors. Ensure that the caliper pistons are properly oriented and that the brake pads are correctly placed. Connect the new brake lines if your conversion kit includes them, making sure all connections are tight and leak-free.

Step 6 Bleed the Brakes

After everything is installed, it’s crucial to bleed the brake system to remove any air from the lines. This ensures optimal brake performance. Start by having a helper pump the brake pedal while you open and close the bleeder valve on each caliper, working from the furthest to the closest caliper.

Step 7 Recheck Everything

Before taking your vehicle out for a test drive, double-check all connections, bolts, and brake fluid levels. Make sure that the new brake system is functioning correctly by pressing the pedal several times.

Conclusion

Converting rear drum brakes to disc brakes can significantly enhance your vehicle's stopping power and safety. While the process requires some mechanical skill, the benefits of improved performance and reliability make it a worthwhile upgrade for many drivers. Always refer to your specific vehicle’s manual and consider consulting with a professional if you feel unsure about any steps in the conversion process.
