Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lift the rear of the vehicle using a jack and jack stands.
Remove the rear wheel to access the brake assembly.

2. Remove Rear Brake Components

Brake Caliper:
- Use a socket wrench to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor and support it using a bungee cord or similar (do not let it hang by the brake line).
Brake Pads:
- Remove the old brake pads from the caliper bracket. Note the orientation for installation of new pads.
Brake Rotor:
- If replacing the rotor, remove the retaining screws (if equipped) and slide the rotor off the hub. If it is stuck, gently tap with a rubber mallet.

3. Inspect and Replace

Inspect Components:
- Check the caliper for any signs of damage or leaking. If damaged, replace the caliper.
Install New Rotor (if applicable):
- Clean the new rotor with brake cleaner to remove any protective oil.
- Slide the new rotor onto the hub and secure it with retaining screws.
Install New Brake Pads:
- Apply a small amount of brake grease to the back of the new pads to reduce noise.
- Install the new brake pads into the caliper bracket.

4. Reassemble and Test

Reattach Brake Caliper:
- Carefully position the caliper over the new pads and rotor.
- Reinstall and torque the caliper mounting bolts to the manufacturer’s specifications (typically around 25-35 ft-lbs).
Final Checks:
- Reinstall the wheel and torque the lug nuts in a star pattern to the specified torque (usually around 80-100 ft-lbs).
- Lower the vehicle and pump the brake pedal several times to seat the new pads.
