Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, dial indicator, torque wrench, brake cleaner, and a multimeter.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the vehicle's battery to prevent any electrical issues during the repair.

2. Remove Wheel

Loosen the lug nuts on the affected wheel using a socket wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Remove Brake Components

Inspect Brake Rotors:
- Use a dial indicator to measure rotor runout. If it exceeds manufacturer specifications, replace the rotor.
Remove Brake Pads:
- Remove caliper bolts with a socket wrench. Carefully slide the caliper off the rotor.
- Remove the brake pads from the caliper bracket. Check for uneven wear and replace if necessary.
Check Caliper Operation:
- Ensure that the caliper piston moves freely. If it is sticking, clean or replace the caliper.

4. Replace Rotors and Pads (if necessary)

If rotors are warped or worn beyond specifications, replace them.
Install new brake pads, ensuring they sit correctly in the caliper bracket.
Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications.

5. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then tighten the lug nuts to the specified torque setting in a crisscross pattern.
Reconnect the vehicle's battery.
