Solution

1. Preparation

Gather necessary tools and parts for the repair.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Gather safety equipment (gloves, goggles).

2. Lift the Vehicle

Use a jack to lift the rear of the vehicle.
Secure with jack stands for safety.
Remove the rear wheels using a socket set.

3. Inspect and Remove Brake Components

Remove the brake caliper by loosening the caliper bolts using a socket wrench.
- Tools Required: Socket set, torque wrench.
Carefully slide the caliper off the rotor and support it using a bungee cord or rope to avoid strain on the brake line.
Remove the brake pads from the caliper bracket.

4. Inspect and Replace Brake Pads and Rotors

Check the brake pads for wear; if they are worn below the minimum thickness, replace them.
Inspect the rotors for damage; if they are warped or excessively worn, replace them.
- Parts Required: New brake pads, new rotors (if necessary).
If replacing rotors, remove the caliper bracket by unscrewing the bracket bolts.
Remove the rotor from the hub, and clean the hub surface.

5. Reassemble Components

Install new rotors (if applicable) onto the hub.
Reattach the caliper bracket and torque the bolts to the manufacturer’s specifications.
Install new brake pads into the caliper bracket.
Reposition the brake caliper over the pads, ensuring it slides smoothly and is properly aligned.
Tighten the caliper bolts to the specified torque.

6. Final Steps

Reinstall the rear wheels and lower the vehicle.
Pump the brake pedal several times to seat the pads against the rotors before driving.
Check brake fluid level and top off if necessary.
