Solution

1. Preparation

Gather tools and parts for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety during repairs.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands
Loosen the lug nuts slightly while the wheel is still on the ground.
Raise the vehicle using a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Rotors (if warped)

Tools Required: Torque wrench, brake cleaner
Use a run-out gauge to measure the rotor for warping. If the run-out exceeds specifications, replace the rotor.
Remove the caliper by unbolting it from the bracket; hang it securely to prevent strain on the brake line.
Remove the rotor from the hub; clean the hub surface with brake cleaner before installing a new rotor.
Install the new rotor, ensuring it is seated correctly.

4. Inspect and Replace Brake Pads (if worn unevenly)

Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and apply brake grease to the contact points.
Install new brake pads, ensuring they are properly positioned.

5. Reassemble Wheel and Lower Vehicle

Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications.
Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified torque setting.

6. Final Checks

Reconnect the battery and perform a test drive to ensure the issue is resolved.
Monitor for any abnormal noises or vibrations during braking.
