Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and place wheel chocks in front of the front wheels.
Loosen the lug nuts on the rear wheels slightly while the car is still on the ground.

2. Raise the Vehicle

Use a hydraulic jack to lift the rear of the vehicle and secure it with jack stands.
Remove the rear wheels by fully loosening and removing the lug nuts.

3. Remove Brake Caliper

Use a socket wrench to remove the bolts securing the brake caliper to the mounting bracket.
Carefully slide the caliper off the rotor and support it using a bungee cord or a suitable hook to avoid strain on the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket. Note their orientation for installation of new pads.
If necessary, compress the caliper piston using a C-clamp to allow for new pads.
Install the new brake pads in the same orientation as the old ones.

5. Inspect and Replace Brake Rotor (if needed)

If the rotor is worn or scored, remove the retaining screws and slide the rotor off the hub.
Clean the hub surface and install the new rotor, securing it with screws.

6. Reassemble Brake Components

Reattach the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's torque specifications (usually around 25-30 ft-lbs).
Reinstall the rear wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully lower the vehicle and remove the jack stands.
Tighten the lug nuts in a crisscross pattern to the manufacturer's torque specification (typically around 76 ft-lbs).
