Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the battery to prevent any electrical issues during the repair.

2. Wheel Removal

Sub-steps:
1. Loosen the lug nuts on the affected wheel using a lug wrench.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Brake Inspection

Sub-steps:
1. Inspect the brake pads for thickness; replace if below manufacturer specifications.
2. Check the brake rotors for any grooves or scoring; replace if necessary.
3. Ensure that all components are clean and free from debris.

4. Component Replacement

Sub-steps:
1. If brake pads are worn, remove the caliper bolts using a socket set and slide the caliper off the rotor.
2. Replace the brake pads with new ones, ensuring they are aligned properly.
3. If rotors are damaged, remove the rotor from the hub by unscrewing any retaining screws and replacing with new rotors.
4. Reinstall the brake caliper over the new pads and torque the caliper bolts to the manufacturer's specifications (typically around 20-30 ft-lbs).

5. Reassembly and Testing

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually 80-100 ft-lbs).
3. Reconnect the battery and perform a test drive to ensure proper operation of the brakes.
