Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues while working on the brake system.

2. Wheel Removal

Use a socket set to loosen the lug nuts on the affected wheel.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Brake Pad Inspection and Replacement

Inspect Pads: Check for uneven wear. If pads are significantly worn, proceed to replace them.
Remove Brake Caliper:
- Use a socket to remove the caliper mounting bolts.
- Slide the caliper off the rotor, supporting it with a bungee cord or rope to avoid strain on the brake line.
Remove Old Brake Pads: Remove the old pads from the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the back of new pads to prevent squeaking.
- Slide the new pads into the caliper bracket.
Reinstall Caliper: Position the caliper over the new pads and secure it with the mounting bolts. Torque to manufacturer specifications.

4. Rotor Inspection and Replacement

Check Rotor: Measure the thickness of the rotors. If they are below the minimum thickness or have significant scoring, replace them.
Remove Rotor: If necessary, remove any retaining screws and slide the rotor off the hub.
Install New Rotor: Position the new rotor onto the hub and secure it with retaining screws if applicable.

5. Brake System Reassembly

Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
Reconnect the battery.
