Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts on the rear wheel with a socket set.
2. Lift the vehicle with a jack and secure it on jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Remove Brake Components

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the rotor; support it with a bungee cord to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. If necessary, remove the caliper bracket by unbolting it.

4. Inspect and Replace Parts

Sub-steps:
1. Inspect the brake rotor for any scoring or excessive wear; if damaged, replace.
2. If the rotor is acceptable, clean it with brake cleaner.
3. Install new brake pads into the caliper bracket.
4. If caliper pistons are extended, compress them using a brake caliper tool.

5. Reassemble and Test

Sub-steps:
1. Reattach the caliper over the new brake pads.
2. Tighten caliper bolts to manufacturer's torque specifications (typically 80-100 ft-lbs).
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and tighten the lug nuts in a crisscross pattern to the specified torque.
