Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety.

2. Remove Wheel

Loosen lug nuts with a socket wrench (do not completely remove yet).
Lift the vehicle using a jack and secure it on jack stands.
Remove lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Remove the caliper bolts with a socket wrench.
- Slide the caliper off and inspect the pads for wear. Replace if worn below minimum thickness.
Inspect and Replace Rotors:
- Check the rotor for thickness and warping using a micrometer. Replace if warping exceeds manufacturer specifications.
- If replacing, remove the rotor retaining screws (if applicable) and pull the rotor off the hub.
- Install new rotors, ensuring they are clean and free of debris.
Reassemble Caliper:
- Reinstall the caliper over the new pads and rotor.
- Torque caliper bolts to manufacturer specifications.

4. Check Suspension and Alignment

Inspect suspension components, including tie rods and control arms, for wear and damage.
If necessary, replace any damaged parts.
After repairs, perform a wheel alignment to ensure proper tracking.

5. Reassemble and Test

Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and torque lug nuts to manufacturer specifications.
Reconnect the battery and perform a test drive to ensure the issue is resolved.
