Solution

1. Preparation

Gather necessary tools: lug wrench, jack, jack stands, caliper gauge, and flashlight.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and securely place it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Pads

Locate the brake caliper and use a caliper gauge to measure the pad thickness.
If the thickness is less than 3mm, replacement is necessary.
Check for uneven wear or damage on the pads.

4. Inspect Brake Rotors

Visually examine the rotors for any deep grooves, scoring, or rust.
Use a micrometer to measure rotor thickness; ensure it meets manufacturer specifications.

5. Reassemble

If pads are acceptable, reinstall the wheel, tightening the lug nuts by hand.
Lower the vehicle from the jack stands and use the torque wrench to tighten lug nuts to the manufacturer’s specified torque (typically around 90-100 ft-lbs).
Replace any components as necessary.
