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 if electrical components are involved.

2. Inspect Brake Pads and Rotors

Remove the wheel using a socket set.
Inspect the brake pads for thickness; replace if less than 3mm.
Check the brake rotors for grooves or scoring. If significant wear is present, they may need resurfacing or replacement.

3. Measure Rotor Run-Out

Use a dial indicator to measure the run-out of the rotors.
If run-out exceeds manufacturer specifications (usually 0.002 inches), replace or machine the rotors.

4. Check Brake Calipers

Inspect calipers for signs of sticking or uneven movement.
Clean and lubricate the caliper slides if necessary, or replace the caliper if it's damaged.

5. Wheel Alignment and Balance

Perform a wheel alignment check and adjust as needed.
Balance the wheels to ensure even tire wear and handling.
