Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, dial indicator (for rotor measurement).
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Loosen lug nuts with a lug wrench while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper by unscrewing the caliper bolts.
- Slide the caliper off the rotor and hang it securely to avoid strain on the brake line.
- Inspect the brake pads for uneven wear; replace if worn unevenly.
Brake Rotors:
- Use a dial indicator to measure the thickness of the brake rotor at several points.
- If the rotor is warped (exceeds manufacturer’s specifications), replace it. If it’s within specs but scored, consider resurfacing.

4. Suspension Check

Inspect control arms, bushings, and struts for any signs of wear or damage.
Replace any worn components as needed to ensure proper alignment and handling.

5. Reassemble and Torque

Reinstall the brake caliper and ensure it is secured with the bolts to the manufacturer’s torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to tighten the lug nuts to the manufacturer’s recommended torque.
