Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, engage the parking brake, and place wheel chocks behind the rear wheels.
Gather tools: socket set, torque wrench, brake cleaner, and safety goggles.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle with a jack and secure with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts using a socket.
- Carefully slide the caliper off the rotor.
- Inspect the brake pads for thickness; replace if less than 3 mm.
Replacement:
- If necessary, remove the old brake pads by pulling them out of the caliper bracket.
- Clean the caliper bracket and apply brake grease to the contact points of the new pads.
- Insert new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check rotor thickness and surface condition with a micrometer.
If rotors are warped or below the minimum thickness, remove them by unscrewing the rotor mounting screws.
Install new rotors, ensuring they are clean of any oils or contaminants. Torque to manufacturer's specifications.

5. Reassemble and Test

Reinstall the caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer's torque specifications.
Reinstall the wheel and torque the lug nuts in a criss-cross pattern.
Lower the vehicle and pump the brake pedal a few times to seat the brake pads.
