How to Change Drum Brakes to Disc Brakes in a Car

Upgrading your vehicle's brake system from drum brakes to disc brakes can significantly enhance your car's stopping power and overall performance. Disc brakes offer better heat dissipation, reduced braking distance, and improved responsiveness, making them a popular choice for car enthusiasts and those looking for improved safety. This guide will outline the steps necessary to change drum brakes to disc brakes in a car.

Tools and Materials Needed

Before beginning the conversion, ensure you have the necessary tools and materials

- New disc brake setup (calipers, rotors, pads, and mounting brackets) - Brake fluid - Brake line fittings - Wrenches and sockets (metric or SAE, depending on your car) - Torque wrench - Jack and jack stands - C-clamp - Screwdrivers - Brake cleaner - Safety goggles and gloves

Step 1 Preparation

1. Safety First Park your car on a flat surface and engage the parking brake. Wear safety goggles and gloves to protect yourself from brake dust and fluids. 2. Loosen Lug Nuts Before raising the vehicle, loosen the lug nuts on the wheels where you'll be working. 3. Lift the Vehicle Use a jack to lift the car and secure it on jack stands. Ensure the vehicle is stable before you proceed.

1. Remove the Wheel Take off the wheel to access the brake assembly. 2. Detach the Brake Drum Use a screwdriver or pry bar to gently remove the drum. If it’s stuck, you may need to tap it lightly with a hammer to free it. 3. Disconnect the Brake Components Remove the springs, shoes, and any other components connected to the drum brakes. Take pictures as you disassemble to help with reassembly later.

Step 3 Install the Disc Brake Components

1. Mount the Bracket Install the bracket that will hold the caliper in place. It should line up with existing mounting points on the axle or control arm. 2. Attach the Caliper Install the disc brake caliper to the bracket. Make sure you have the correct orientation; refer to manufacturer instructions if necessary. 3. Install the Rotor Place the new rotor over the hub. It should fit snugly against the bracket. 4. Secure the Caliper Place the brake pads inside the caliper and secure it onto the rotor, ensuring that everything is tightened to the proper torque specifications.

Step 4 Brake Lines and Fluid

1. Connect Brake Lines If your new disc brake setup requires different brake lines, install those now. Make sure all connections are tight to prevent leaks. 2. Bleed the Brakes With the new brakes installed, you’ll need to bleed the brake system to remove any air. Start at the wheel farthest from the master cylinder and work your way to the nearest. Have a helper pump the brake pedal while you open and close the bleeder valve until fluid flows without bubbles. 3. Check Brake Fluid Levels Ensure the brake fluid reservoir is filled to the correct level, adding fluid as necessary.

Step 5 Reassemble and Test

1. Reattach the Wheel Once everything is installed and torqued to spec, reattach the wheel and lower the vehicle. 2. Test the Brakes Start the car and test the brakes gently before taking it for a drive. Feel for any abnormalities such as grinding or pulling, which may indicate improper installation.

Conclusion

Converting drum brakes to disc brakes can be a rewarding project that enhances your vehicle's performance. While the process may seem complex, careful attention to detail and adherence to safety protocols will ensure a successful upgrade. Always consult your vehicle's service manual and consider seeking professional assistance if you are uncertain about any steps in the process. Enjoy your enhanced braking power!
