Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, dial indicator, brake cleaner, safety glasses, gloves.
Safety Warnings: Ensure the vehicle is on a level surface and the parking brake is engaged before lifting.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Jack up the vehicle and secure it on 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.
- Check the thickness of the brake pads and inspect for uneven wear. Replace if necessary.
Brake Rotors:
- Use a dial indicator to measure the runout of the rotor. If the runout exceeds manufacturer's specifications, replace the rotor.
- Check for scoring or grooves; if present, consider resurfacing or replacing the rotor.

4. Inspect Suspension and Wheel Bearings

Examine control arms and bushings for any signs of wear or damage.
Check wheel bearings for play by rocking the wheel at 12 and 6 o’clock and 3 and 9 o’clock positions; replace if any play is detected.

5. Reassemble and Torque

Reinstall the brake caliper and ensure it’s properly seated.
Replace the wheel, hand-tighten the lug nuts, and lower the vehicle.
Torque the lug nuts to the manufacturer's specifications in a star pattern.
