Solution

1. Preparation

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

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Lift the vehicle with a jack and secure it on jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set and slide the caliper off the rotor.
Check the brake pads for wear; if they are below manufacturer specifications (usually less than 3mm), replace them.
If replacing, remove the old pads and install new pads, ensuring they are seated correctly.
Apply brake grease to the backing of the new pads to reduce noise.

4. Inspect and Replace Brake Rotors (if necessary)

Check the thickness of the rotors with a micrometer. If they are below the minimum thickness spec, they should be replaced.
If replacing, remove the rotor by unscrewing the retaining screws and sliding it off the hub.
Install the new rotor, ensuring it is clean and free of debris.

5. Reassemble Components

Reattach the caliper over the new brake pads and rotor, tightening the caliper bolts to the manufacturer's torque specification (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Carefully lower the vehicle off the jack stands.
Tighten the lug nuts to the manufacturer's specified torque (usually 76 ft-lbs).
Reconnect the battery.
