Converting Rear Drum Brakes to Disc Brakes A Step-by-Step Guide

Upgrading rear drum brakes to disc brakes can enhance your vehicle's braking performance, improve heat dissipation, and offer a more consistent pedal feel. While the task may seem daunting, with the right tools and guidance, you can accomplish it successfully. Here’s a step-by-step guide on how to convert rear drum brakes to disc brakes.

1. Gather Necessary Tools and Parts

Before you begin the conversion, gather all essential tools and parts. You will need

- A disc brake conversion kit (specific to your car model) - Socket set and wrenches - Brake cleaner - Brake fluid - Jack and jack stands - Torque wrench - Safety glasses and gloves

2. Lift the Vehicle

Start by safely lifting the vehicle with a jack and securing it on jack stands. Ensure that the car is on a flat, stable surface to prevent any accidents.

3. Remove the Rear Wheels

Once the vehicle is securely elevated, remove the rear wheels using a lug wrench. This will give you access to the drum brakes.

4. Take Off the Drum Brakes

Unscrew and carefully remove the brake drums. You may need to tap them lightly with a hammer if they are stuck. Once the drums are off, take out the shoes, springs, and other components carefully. Remember to keep all parts in case you need to refer back to them.

5. Install the Rear Disc Brake Components

Now, it's time to install the disc brake components. First, attach the new brake backing plates to the axle housing. Then, mount the new calipers to the backing plates. Follow the instructions provided in your conversion kit closely to ensure that each component is installed correctly. If spacers are included, suggest using them according to the kit specifications.

6. Install the Brake Rotors

Once the calipers are secured, slide the brake rotors over the wheel hubs. Ensure that they fit snugly and are properly centered.

7. Connect the Brake Lines

Next, connect the brake lines to the new calipers. Make sure to use a line wrench to avoid striping the fittings. Check for any leaks after installation; this is crucial for safety.

8. Bleed the Brakes

After connecting everything, bleed the brakes to remove any air from the system. This step is vital to ensure optimal brake performance. Press the brake pedal a few times, then open the bleeder valve on the caliper to let fluid escape. Repeat this until you see a steady stream of brake fluid without air bubbles.

9. Reinstall the Wheels and Lower the Vehicle

Once everything is connected and bled, reinstall the rear wheels and lower the vehicle carefully.

10. Test Drive

Finally, take your vehicle for a test drive in a safe area to ensure that the new disc brakes are functioning correctly. Check for noise and braking efficiency, and make further adjustments if necessary.

Upgrading from drum to disc brakes can greatly enhance your vehicle's braking capability, handling, and overall safety. By following this guide, you can successfully make the conversion and enjoy the benefits of modern braking technology.
