Steps to Convert Drum Brakes to Disc Brakes on Your Vehicle

How to Change from Drum Brakes to Disc Brakes

Upgrading from drum brakes to disc brakes is a popular modification among car enthusiasts looking to improve their vehicle's performance and safety. Disc brakes offer superior stopping power, better heat dissipation, and reduced brake fade, making them a worthwhile investment. Here’s a step-by-step guide on how to make this transition.

Step 1 Gather Your Tools and Materials

Before you start, ensure you have all the necessary tools a jack, jack stands, wrenches, sockets, brake cleaner, and a torque wrench. You'll also need replacement disc brake components, including calipers, rotors, brake pads, a new master cylinder (if necessary), and brake lines. Consult your vehicle’s manual for specific parts compatible with your make and model.

Step 2 Safety First

Begin by parking your vehicle on a flat surface and engaging the parking brake. Loosen the lug nuts of the rear wheels slightly while it’s still on the ground. Next, use a jack to lift the rear of the vehicle and secure it with jack stands. Remove the wheels to access the drum brakes.

Step 3 Remove the Drum Brakes

With the wheels removed, locate the brake drums. Detach the brake drum by removing the screws or bolts holding it in place. Once the drum is off, take out the brake shoes and any associated hardware. Note how everything is assembled as you will need this information for the installation of the new components.

Install the new disc brake components by first mounting the brake backing plate, if necessary. Secure it to the vehicle’s frame. Then, position the new rotor onto the hub and secure it using the appropriate hardware. Make sure it fits snugly and is properly aligned.

Step 5 Mount the Calipers

Next, install the calipers over the rotors. Ensure that the caliper brackets are securely fastened to the backing plate. Then, insert the brake pads into the caliper bracket, ensuring they are positioned correctly for optimal contact with the rotor.

Step 6 Replace the Master Cylinder

Since drum and disc brakes operate differently, you may need to upgrade the master cylinder to ensure adequate hydraulic pressure. Remove the old master cylinder by unbolting it from the brake booster. Then, install the new master cylinder and connect the brake lines securely.

Step 7 Bleed the Brakes

After everything is connected, it’s crucial to bleed the brake lines to eliminate any air trapped in the system. Start from the wheel farthest from the master cylinder and work your way to the closest wheel. Use a bleeder valve to release brake fluid until you see consistent fluid without air bubbles.

Step 8 Test the Brakes

Finally, reattach the wheels and lower your vehicle. Before taking it back on the road, pump the brakes a few times to ensure they are responding correctly. It's essential to perform a test drive in a safe area to familiarize yourself with the new braking system.

Conclusion

Changing from drum brakes to disc brakes can significantly enhance your vehicle's braking performance. By following these steps and prioritizing safety, you can enjoy improved stopping ability and more responsive handling. Always consult your vehicle’s manual for specific instructions and specifications related to your car model. Happy driving!
