How to Change Rear Drum Brakes to Disc Brakes
Upgrading your vehicle's rear drum brakes to disc brakes can significantly enhance braking performance, heat dissipation, and overall driving safety. Here’s a step-by-step guide on how to make this conversion effectively.
Step 1 Gather Tools and Materials
Before embarking on this project, ensure you have all the necessary tools and components. You will need
- New rear disc brake assembly (calipers, rotors, brackets) - Brake lines and hoses - Brake fluid - Socket set and wrenches - Jack and jack stands - Brake cleaner - Bungee cords or straps - Torque wrench
Step 2 Prepare the Vehicle
Begin by parking your vehicle on a flat surface. Use a jack to lift the rear of the car and secure it with jack stands. Remove the rear wheels to gain access to the brake components.
Step 3 Remove Drum Brake Components
Carefully detach the drum brake assembly. This involves removing the brake drum, which may require some light tapping with a hammer if it’s stuck. After the drum is off, take out the shoes, springs, and any other associated hardware. Make sure to note how components are arranged for reference during assembly.
Step 4 Install the Disc Brake Bracket
The disc brake conversion kit should come with brackets specifically designed for your vehicle. Attach the disc brake mounting bracket to the rear axle using the supplied hardware. Ensure everything is tightened properly to handle brake forces.
Step 5 Install Rotors and Calipers
Slide the new brake rotors onto the wheel hub, making sure they are seated correctly. Then, install the calipers over the rotors following the manufacturer’s instructions. Secure the calipers using the provided bolts, ensuring they are torqued to the specifications.
Step 6 Connect Brake Lines
Locate your existing brake lines and adapt them for the new disc brake setup, if necessary. If your kit includes new brake hoses, install them according to the instructions. Make sure there are no leaks and all connections are tight.
Step 7 Bleed the Brakes
Once everything is installed, it’s crucial to bleed the braking system to remove any air. This step ensures proper brake function. Fill the master cylinder with brake fluid and have an assistant pump the brake pedal while you open and close the bleeder valves on the calipers.
Step 8 Final Checks and Test Drive
Before hitting the road, double-check all your connections and ensure that everything is secured. Replace the wheels and lower the vehicle. After a quick test of the brakes at low speed in a safe area, you can begin using your upgraded braking system confidently.
Conclusion
Converting from drum to disc brakes can be a rewarding project that improves safety and performance. With careful attention to detail and the proper tools, you can successfully enhance your vehicle’s braking system.
