Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Raise Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brake pads are being inspected.
Secure with jack stands for safety.

3. Remove Wheel

Use a lug wrench to remove the wheel lug nuts.
Take off the wheel to access the brake components.

4. Inspect Brake Pads and Components

Visually inspect brake pads for uneven wear.
- If one pad is significantly thinner than the other, it may need replacement.
Check the rotors for warping or uneven surfaces.
Inspect the caliper for any signs of sticking or failure.
- If caliper slides are not moving freely, clean and lubricate them.

5. Replace or Adjust Components

If brake pads are unevenly worn, replace them with new pads.
- Use pads that meet OEM specifications for quality.
If the caliper is sticking, consider rebuilding or replacing it.
If rotors are warped, resurface or replace them as needed.

6. Reassemble

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).

7. Test Brake System

Pump the brake pedal to seat the new pads if applicable.
Conduct a test drive to ensure proper braking performance and check for any pulling or noise.
