Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal.

2. Remove Wheel

Using a jack, raise the vehicle and secure it with jack stands.
Remove the lug nuts with a socket wrench and take off the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Inspection: Check the thickness of the brake pads. If they are below 3mm, replace them.
Removal:
1. Remove the caliper bolts using a socket wrench.
2. Slide the caliper off the rotor and hang it using a bungee cord (do not let it dangle from the brake line).
3. Remove the old brake pads from the caliper bracket.
Installation:
1. Apply brake grease to the backing of the new pads.
2. Install the new brake pads into the caliper bracket.
3. Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer’s specified torque (usually around 25-35 ft-lbs).

4. Inspect and Resurface/Replace Rotors

Inspection: Check for grooves or warping on the rotors.
Resurfacing: If the rotors are within the minimum thickness specification, take them to a machine shop for resurfacing.
Replacement: If the rotors are excessively worn, remove them by loosening the retaining screws and slide them off the hub. Install new rotors by reversing the removal steps.

5. Reassemble and Test

Reattach the wheel and lug nuts, tightening them in a criss-cross pattern to the manufacturer's torque specification.
Lower the vehicle and reconnect the negative battery terminal.
