Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Wear safety gloves and goggles for protection.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes you are checking.
Secure the vehicle with jack stands to ensure safety.

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 check the brake pads; they should be at least 3mm thick. If thinner, they need replacing.
Use a caliper to measure the thickness accurately.
Check for uneven wear which may indicate caliper issues.

5. Inspect Brake Rotors

Examine the rotors for any signs of scoring, rust, or warping.
Use a micrometer to measure rotor thickness; it should not be below the manufacturer's minimum specification.

6. Reassemble

If all components are in good condition, reassemble the wheel.
Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications.

7. Test Brake System

Start the vehicle and gently press the brakes to ensure everything is functioning correctly.
Check for any unusual noises or vibrations during a short test drive.
