Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Wheel Removal

Use a lug wrench to loosen the lug nuts slightly while the vehicle is still on the ground.
Once loosened, lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Brake Component Inspection

Brake Rotors:
- Use a dial indicator to measure rotor runout. If it exceeds manufacturer specifications, replace the rotors.
Brake Pads:
- Measure the thickness of the brake pads. If they are below the minimum thickness, replace them.
Caliper Function:
- Check for free movement of the caliper. If it is stuck or dragging, it may need to be serviced or replaced.

4. Replace Components

If rotors are warped, remove them by loosening the retaining screws and sliding them off the hub.
Install new rotors and torque to the manufacturer's specifications (typically around 100-130 ft-lbs).
Replace brake pads, ensuring they are seated properly in the caliper bracket.
Reinstall calipers and torque bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).
Reconnect the battery and test drive the vehicle to ensure the issue is resolved.
