Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery negative terminal for safety.

2. Inspect and Replace Rear Brake Components

Remove the Wheel
- Use a jack to lift the rear of the vehicle.
- Secure with jack stands.
- Remove the wheel lug nuts using a socket set.
- Remove the wheel and set aside.
Inspect Brake Pads and Rotors
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor; support it with a bungee cord to avoid straining the brake line.
- Inspect the brake pads for thickness; replace if below 3mm.
- Check the rotor for grooves or warping; replace if damaged.
Install New Brake Pads and Rotor (if necessary)
- If replacing pads, compress the caliper piston using a caliper tool.
- Install new pads in the caliper bracket.
- If replacing the rotor, remove the rotor and install the new one, ensuring it is properly seated.
Reassemble the Brake Caliper
- Reattach the caliper over the new pads and rotor.
- Tighten caliper bolts to the manufacturer's specified torque (usually around 25-30 ft-lbs).
- Reinstall the wheel and lug nuts, tightening them in a crisscross pattern to the recommended torque.

3. Inspect and Replace Wheel Bearings (if needed)

Remove the Brake Components
- Repeat steps from "Inspect Brake Pads and Rotors" to access the hub bearing.
Check Wheel Bearing
- Inspect for play by rocking the wheel side-to-side.
- If rough or loose, remove the hub assembly.
Install New Wheel Bearing
- Using a bearing puller, remove the old bearing.
- Clean the hub area and install the new bearing, ensuring proper orientation.
- Reassemble the hub and brake components as previously described.
