Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Remove Wheel

Use a lug wrench to loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely 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 carefully lift the caliper off the rotor.
Support the caliper with a bungee cord or similar to avoid straining the brake line.
Remove the old brake pads; clean the caliper bracket and inspect it for any debris.
Install new brake pads, ensuring they are oriented correctly.
Reinstall the caliper over the new pads and secure it with the caliper bolts, tightening to manufacturer specifications.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are scored or warped, remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Clean the hub surface before installing the new rotor.
Install a new rotor, ensuring it is seated properly.
Replace any retaining screws if applicable.

5. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts to the specified torque.
Repeat for the opposite side if applicable.
