Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Lift the Vehicle

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

3. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to expose the brake assembly.

4. Inspect Brake Pads

Visually inspect the brake pads; thickness should be at least 1/8 inch (approximately 3 mm).
If necessary, use a caliper to measure the thickness of the brake pads.
Inspect for uneven wear or cracks in the pads.

5. Check Brake Rotors

Inspect the rotors for any signs of scoring or uneven surfaces.
If the rotor surface is damaged or excessively worn, it may need resurfacing or replacement.

6. Reassemble

If brake pads are still within acceptable limits, reinstall the wheel and lug nuts.
If pads need replacement, follow the replacement procedure (not covered here) and then reassemble.

7. Lower the Vehicle

Carefully lower the vehicle back to the ground and torque the lug nuts to the manufacturer's specifications.
