Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Loosen the rear wheel lug nuts slightly before lifting the vehicle.

2. Lift the Vehicle

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

3. Inspect and Replace Brake Pads

Remove Brake Caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor and suspend it using a bungee cord to prevent stress on the brake line.
Remove Old Brake Pads:
- Slide the old brake pads out of the caliper bracket.
Install New Brake Pads:
- Insert new brake pads into the caliper bracket.
- Ensure the pads are properly seated and aligned.

4. Inspect and Replace Brake Rotors (if necessary)

Remove Brake Rotor:
- If the rotor is scored or warped, remove it by unscrewing any retaining screws and pulling it off the hub.
Install New Brake Rotor:
- Clean the new rotor with brake cleaner to remove any protective coating.
- Install the new rotor onto the hub, ensuring it is properly seated.

5. Reassemble Brake Assembly

Reinstall the brake caliper over the new brake pads.
Tighten caliper mounting bolts to the manufacturer’s specified torque (typically around 20-25 ft-lbs).

6. Final Checks

Reinstall the rear wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (typically around 80-100 ft-lbs).
Refill brake fluid if necessary and bleed the brakes to remove air from the system.
