Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels.

2. Brake Inspection and Repair

Remove Wheel
- Use a lug wrench to loosen and remove lug nuts.
- Lift the vehicle using a jack and secure it with jack stands.
Inspect Brake Components
- Remove the brake caliper by unscrewing the caliper bolts with a socket set.
- Check the brake pads for thickness; replace if worn below the minimum thickness.
- Inspect the brake rotor for scoring or warping; replace if necessary.
Reassemble
- Reinstall the caliper and torque bolts to manufacturer specifications (usually around 20-25 ft-lbs).
- Reattach the wheel and hand-tighten the lug nuts.

3. Wheel Bearing Replacement (if necessary)

Remove Wheel
- Repeat the wheel removal procedure as above.
Remove Hub Assembly
- Remove the axle nut using a socket.
- Disconnect any brake lines or sensors attached to the hub.
- Unscrew the hub assembly bolts and remove the hub.
Replace Bearing
- Press out the old bearing using a bearing puller.
- Press in the new bearing, ensuring it is properly seated.
Reassemble
- Reinstall the hub assembly and torque bolts to specification.
- Reattach the axle nut and torque it to manufacturer specifications (usually around 150 ft-lbs).
