Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts with a lug wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection:
- Check the thickness of the brake pads. If they are less than 3mm, they need replacement.
Replacement:
- Remove the caliper bolts using a socket set and carefully slide the caliper off.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are oriented correctly.
- Compress the caliper piston using a brake caliper tool to allow for new pads.
- Reattach the caliper and torque the bolts to the manufacturer’s specifications (typically around 20-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored or damaged:
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
- Replace with new rotors, ensuring that they are clean and properly seated.
- Torque the retaining screws as recommended (usually around 7-10 ft-lbs).

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and remove them.
Tighten the lug nuts to the manufacturer’s specifications (typically around 76-80 ft-lbs in a crisscross pattern).
