Solution

1. Preparation

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

2. Inspect Brake Pads and Rotors

Sub-steps:
1. Remove the wheel using a lug wrench.
2. Inspect brake pads for thickness; replace if below 3 mm.
3. Measure rotor thickness and runout with a dial indicator; replace rotors if warped (more than 0.005 inches).
4. Clean the rotor surface with brake cleaner if necessary.

3. Check Wheel Alignment

Sub-steps:
1. Inspect tire pressure; inflate to manufacturer specifications.
2. Look for uneven tire wear patterns indicating alignment issues.
3. If needed, take the vehicle to a professional for alignment adjustment.

4. Test Brake Fluid

Sub-steps:
1. Check the brake fluid reservoir level; top off with the correct type (DOT 3 or DOT 4).
2. Inspect brake fluid for discoloration or contaminants; if dirty, perform a brake fluid flush.

5. Reassemble and Torque Components

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically 100-110 ft-lbs).
