How to Replace Drum Brakes with Disc Brakes A Comprehensive Guide

Upgrading your vehicle's braking system from drum brakes to disc brakes can dramatically improve braking performance, reduce brake fade, and enhance safety. While this task requires some mechanical knowledge and tools, it can be manageable for DIY enthusiasts. Here’s a step-by-step guide on how to replace drum brakes with disc brakes.

Step 1 Gather Your Tools and Materials

Before starting the conversion, ensure you have the necessary tools and materials. You will need

- Disc brake conversion kit (specific to your vehicle model) - Basic hand tools (screwdrivers, wrenches, pliers) - Jack and jack stands - Brake cleaner - New brake pads and rotors (if not included in the kit) - Brake fluid

Step 2 Safety First

Safety is paramount when working on your vehicle. Park the car on a level surface and engage the parking brake. Use a jack to lift the vehicle and secure it with jack stands. Always wear gloves and safety glasses to protect yourself during the process.

Step 3 Remove the Drum Brakes

1. Remove the wheel Use a lug wrench to loosen and remove the lug nuts, then take off the wheel to access the brake assembly. 2. Disconnect the brake line Carefully disconnect the brake line from the wheel cylinder. Have a container ready to catch any leaking brake fluid. 3. Remove the drum If the drum is stuck, gently tap it with a rubber mallet to loosen it. Once free, remove the drum to access the brake shoes and hardware. 4. Take out the brake shoes and hardware Remove the springs and other components holding the brake shoes in place. Pay close attention to how they are assembled, as you will need to refer to this during the installation of the new system.

1. Install the new spindle (if required) Depending on your conversion kit, you may need to replace the spindle. Follow the manufacturer’s instructions for proper installation. 2. Attach the rotor Secure the brake rotor to the new spindle using the provided hardware. 3. Mount the caliper Install the caliper bracket and caliper onto the rotor. Ensure it is properly aligned and secured. 4. Install the new brake pads Place the brake pads into the caliper bracket, making sure they fit snugly against the rotor.

Step 5 Reconnect the Brake Line

Reconnect the brake line to the caliper, ensuring a tight and leak-free fit. It is essential to use new copper crush washers if your kit includes them.

Step 6 Bleed the Brakes

After installation, it’s crucial to bleed the brake system to remove any air bubbles from the lines. Start by filling the brake reservoir with new brake fluid. Then, have an assistant pump the brake pedal while you open the bleeder valve on the caliper to release air until only fluid comes out. Repeat for each wheel.

Step 7 Test and Finalize

Once everything is reassembled, reinstall the wheels and lower the vehicle. Before hitting the road, pump the brake pedal several times to ensure the pads seat correctly against the rotor. It’s advisable to test drive in a safe area and gradually get accustomed to the new braking system.

Conclusion

Replacing drum brakes with disc brakes can be a rewarding upgrade that enhances your vehicle's braking capabilities. With the right tools, patience, and an understanding of the process, this conversion can significantly improve your safety and driving experience. Always consult your vehicle’s manual and guidelines specific to your conversion kit for the best results.
