Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel

Use a lug wrench to loosen lug nuts on the wheel where brakes will be serviced.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts with a socket set and slide the caliper off the rotor.
Secure the caliper to a suspension component using wire or a bungee cord (do not let it hang from the brake line).
Remove the old brake pads from the caliper bracket.
Compare new brake pads with old ones to ensure correct sizing.
Apply brake grease to the back of the new pads to prevent squeaking.
Install the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are unevenly worn or scored, remove them by unbolting from the hub.
Clean the hub surface with a wire brush to ensure proper rotor seating.
Install new rotors, ensuring they are torqued to manufacturer specifications.

5. Reassemble and Test

Reinstall the caliper over the new pads and secure with bolts to the manufacturer’s torque specifications.
Reinstall the wheel, hand-tightening the lug nuts.
Lower the vehicle and tighten the lug nuts to the recommended torque specification in a crisscross pattern.
Reconnect the battery and perform a brake function test before driving.
