Solution

1. Preparation

Gather necessary tools including a brake pad thickness gauge and a flashlight.
Ensure the vehicle is parked on a flat surface, and the parking brake is engaged.

2. Access the Wheel

Loosen the lug nuts on the wheel you will inspect using a lug wrench.
Raise the vehicle using a jack and secure it on jack stands.
Remove the wheel by fully unscrewing the lug nuts and taking the wheel off.

3. Inspect Brake Pads

Visually check the brake pads through the caliper.
- If visible, note the thickness of the pad material.
If more detailed inspection is needed, use the brake pad thickness gauge:
- Insert the gauge between the pad and rotor to measure the thickness.
- Consider replacing pads if they are below the manufacturer-recommended thickness (typically around 3mm or less).

4. Check Brake Rotors

Inspect the surface of the rotors for any grooves, scoring, or excessive wear.
Use a micrometer to measure rotor thickness if necessary; replace if below minimum specification.

5. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and torque the lug nuts to the manufacturer's specifications (usually around 100-120 lb-ft).
Test drive the vehicle to ensure proper brake function.
