Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to avoid any electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads: Check the thickness; if worn below manufacturer's specifications, replace them.
Remove Old Pads: Unbolt the caliper using a socket set and slide it off the rotor.
Replace Pads: Install new brake pads in the caliper bracket, ensuring they are seated properly.

4. Inspect and Resurface or Replace Rotors

Check Rotors: If they are below minimum thickness or warped, replace them. Otherwise, consider resurfacing if applicable.
Resurfacing: If resurfacing, take them to a machine shop; ensure they are within the manufacturer's specifications after resurfacing.
Install Rotors: If replacing, mount the new rotors onto the hub, securing them with the appropriate torque.

5. Reassemble and Test

Reattach the caliper over the new pads and rotor, ensuring all bolts are tightened to the manufacturer's torque specifications.
Reinstall the wheel and lug nuts, lowering the vehicle back to the ground.
Reconnect the negative battery terminal.
