Solution

1. Preparation

Gather tools and materials:
- Jack and jack stands
- Lug wrench
- Socket set
- Torque wrench
- Brake cleaner
- New brake pads (if necessary)
- New brake rotors (if necessary)
Safety warning: Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using the jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using the socket set and slide the caliper off the rotor.
If the brake pads are worn below the minimum thickness, remove them from the caliper bracket.
- Sub-step: Clean the caliper bracket with brake cleaner to remove dust and debris.
Install new brake pads into the bracket, ensuring they are correctly positioned.

4. Inspect and Replace Rotors (if necessary)

Check the rotor surface for grooves or warping.
If replacement is needed, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install new rotors, ensuring they are properly seated and clean any contact surfaces.

5. Reassemble Brake Components

Reattach the caliper over the new pads and rotor, ensuring it slides freely.
Tighten caliper bolts to the manufacturer’s torque specifications.

6. Reinstall Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value in a crisscross pattern.
