Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Inspect Brake Pads

Remove the wheel using a socket set.
Check the thickness of the brake pads; replace if they are below the manufacturer's minimum thickness (typically 3mm).
If necessary, replace the brake pads.
- Tools Required: Socket set, brake pad spreader, torque wrench
- Safety Warning: Ensure the vehicle is securely supported before removing any wheels.

3. Check Brake Rotors

After removing the wheel, visually inspect the rotors for signs of warping or scoring.
Use a dial indicator to measure rotor run-out; replace rotors if they exceed the manufacturer’s specifications (usually 0.002 inches).
If they are in good condition, consider resurfacing them if within tolerances.
- Tools Required: Dial indicator, rotor resurfacing machine (if applicable)

4. Inspect Suspension Components

Check for any play in the control arms, bushings, and tie rods by manually moving them.
Replace any worn or damaged components as necessary.
- Tools Required: Socket set, pry bar

5. Wheel Alignment and Balancing

After replacing/repairing components, perform a wheel alignment.
Balance the wheels if necessary to ensure even tire wear and proper handling.
- Tools Required: Alignment rack, wheel balancer
