Diagnostic Steps

1
Visually inspect the brake pads through the wheel spokes for uneven thickness.
2
Check for any abnormal wear patterns on the brake rotors during inspection.
3
Measure the thickness of each brake pad with a caliper or ruler to compare wear levels.
4
Test drive the vehicle to assess braking performance and note any pulling or vibration.
5
Inspect brake calipers for proper operation and any signs of sticking or uneven movement.

Solution

Solution

1. Preparation

Tools Required: Wheel chocks, jack and jack stands, lug wrench, caliper gauge or ruler, brake cleaner, safety glasses, gloves.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the battery for safety, especially if working near electronic components.

2. Lift the Vehicle

Use a lug wrench to loosen the lug nuts on the affected wheel slightly.
Raise the vehicle with a jack and secure it with jack stands.
Remove the wheel completely.

3. Inspect Brake Pads

Examine the brake pads visually for uneven wear. Look for differences in thickness between inner and outer pads.
Use a caliper gauge or ruler to measure the thickness of each brake pad.
Record the measurements to identify any significant disparities indicating uneven wear.

4. Replace Brake Pads (if necessary)

If uneven wear is detected, remove the caliper by loosening the caliper bolts and sliding it off the rotor.
Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and rotor with brake cleaner.
Install new brake pads in the caliper bracket, ensuring they are seated properly.
Reattach the caliper over the new pads and tighten the caliper bolts to manufacturer specifications (typically around 20-25 ft-lbs).
Repeat the process for the other side if necessary.

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Tighten the lug nuts to the manufacturer’s torque specifications (usually around 80-100 ft-lbs).
