Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts while the vehicle is on the ground.
Jack up the vehicle and securely place it on jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads Inspection/Replacement:
- Remove the caliper by unscrewing the caliper bolts. Support it with a bungee cord or rope to prevent strain on the brake line.
- Inspect the brake pads for thickness; replace if less than 3mm.
- If replacing, slide out the old pads and install new pads, ensuring they are properly seated.
Brake Rotor Inspection/Replacement:
- Remove the caliper bracket if necessary to access the rotor.
- Check the rotor for warping or scoring. If warped (more than 0.002 inches), replace the rotor.
- If replacing, remove the old rotor and install the new rotor, ensuring it is secured properly.

4. Reassemble and Torque

Reattach the caliper and bracket, ensuring bolts are torqued to the manufacturer's specifications (typically around 25-35 ft-lbs for caliper bolts).
Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specification (usually 130-150 ft-lbs).
