Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery cable to prevent electrical shorts.

2. Remove Rear Wheel

Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove lug nuts using a socket wrench and take off the rear wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Remove the caliper bolts with a socket wrench.
- Carefully slide the caliper off the rotor and support it without straining the brake line.
- Inspect the brake pads for thickness; replace if below specifications (usually less than 3mm).
Replace Brake Pads (if necessary):
- Remove the old pads from the caliper bracket.
- Install new brake pads into the bracket, ensuring they are seated properly.
Inspect Brake Rotors:
- Check the thickness of the rotors with a micrometer. Replace if worn beyond specifications.
Replace or Resurface Rotors (if necessary):
- If replacing, remove the rotor by unscrewing the retaining screws or clips.
- Install new rotors, ensuring they are properly aligned and secured.

4. Reassemble Brake Components

Reattach the brake caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer torque specifications (usually around 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

5. Refill Brake Fluid

Check and refill the brake fluid reservoir with fresh DOT 3 or DOT 4 brake fluid as needed.
Bleed the brakes if air was introduced into the system, starting from the farthest wheel working towards the master cylinder.

6. Final Checks

Reconnect the negative battery cable.
Lower the vehicle from the jack stands and perform a brake test before road testing.
