Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Wear safety glasses and gloves.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the rear wheel.
Lift the vehicle with a jack and secure it on jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Remove Brake Components

Use a socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the rotor, supporting it with a bungee cord or wire to prevent tension on the brake line.
Remove brake pads from the caliper bracket.

4. Inspect and Replace Parts

Inspect the brake pads for wear; if they are worn down to the indicator, replace them with new pads.
Check the brake rotor for any scoring or warping; if damaged, replace the rotor.
Clean the caliper and bracket with brake cleaner and a wire brush.

5. Reassemble

Install new brake pads into the caliper bracket.
Reattach the caliper over the new pads and torque the caliper mounting bolts to the manufacturer’s specifications (typically 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle

Carefully lower the vehicle back to the ground.
Fully tighten the lug nuts in a crisscross pattern to the manufacturer’s specifications.
