How to Change Rear Drum Brakes to Disc Brakes

Upgrading your vehicle’s rear drum brakes to disc brakes can significantly enhance your braking performance, improve heat dissipation, and provide a more consistent stopping power. While this conversion may sound daunting, with the right tools and a bit of guidance, it can be a rewarding DIY project. Here’s a comprehensive guide on how to make the switch effectively.

Tools and Materials Needed

Before you start, gather the necessary tools and materials

- Jack and jack stands - Lug wrench - Socket set - Brake line wrench - New disc brakes - Calipers and mounting brackets - Brake pads - Brake fluid - Anti-corrosion spray - Basic hand tools (screwdrivers, pliers, etc.) - Torque wrench - Safety glasses and gloves

Step 1 Prepare Your Vehicle

1. Safety First Ensure your vehicle is on a flat surface. Engage the parking brake and put on safety glasses and gloves. 2. Lift the Vehicle Using the jack, lift the rear of the vehicle and secure it with jack stands. Remove the rear wheels using the lug wrench.

Step 2 Remove the Old Drum Brakes

1. Leave the Drum Remove the brake drum by unscrewing the retaining bolts or pulling it off if it is stuck due to corrosion. If necessary, use a hammer to gently tap around the drum's edge to loosen it.

2. Take Out the Brake Shoes Once the drum is off, remove the brake shoes by unhooking the springs and disconnecting any attached hardware. Make sure to note the arrangement for reassembly if required.

3. Remove the Backing Plate Unscrew the backing plate and disconnect any associated components to gain access to the axle.

Step 3 Install the New Disc Brake Kit

1. Attach the New Bracket Begin by attaching the caliper bracket onto the rear axle, aligning it with the existing mounting points. Use the torque wrench to tighten the bolts to the manufacturer’s specifications.

2. Install the Rotors Slide the new rotors onto the rear axle, ensuring they are seated properly against the mounting surface. Secure them with the appropriate hardware.

3. Mount the Calipers Next, install the calipers over the rotors and attach them to the caliper brackets. Make sure to use new caliper mounting bolts and torque them to the specification.

Step 4 Connect Brake Lines and Install New Pads

1. Replace Brake Lines Depending on the kit you purchased, you may need to replace the brake lines. Use a brake line wrench to disconnect the old lines and connect the new ones, ensuring a snug fit to prevent leaks.

2. Insert Brake Pads Install the new brake pads into the caliper bracket. Ensure they are secured correctly and move freely.

Step 5 Bleed the Brakes

1. Adding Brake Fluid Fill the brake reservoir with new brake fluid to eliminate air from the system.

2. Bleed the Brakes Have an assistant pump the brake pedal while you open the bleeder valve on the caliper. Close the valve once fluid starts to flow, and repeat until you see a steady stream of fluid without bubbles.

Step 6 Reassemble and Test

1. Reinstall Wheels Put the wheels back on and lower the vehicle to the ground. Torque the lug nuts to specification.

2. Test Drive Before hitting the road, test the brakes at low speeds in a safe area. Ensure everything works properly, and there’s no noise or pulling.

Conclusion

Converting rear drum brakes to disc brakes can offer numerous benefits in terms of performance and reliability. By following the steps outlined above and using the appropriate tools, you can complete this conversion with relative ease. Always remember to prioritize safety and double-check your work to ensure your vehicle remains in top condition. Happy driving!
