Solution

1. Preparation

Gather necessary tools and safety gear.
Ensure the vehicle is parked on a flat surface and the engine is off.
Use wheel chocks to prevent the vehicle from rolling.

2. Remove Wheel

Loosen lug nuts with a lug wrench before lifting the vehicle.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and inspect the brake pads for wear; replace if worn below 3mm.
Replacement:
- If replacing, compress the caliper piston using a caliper tool.
- Install new brake pads with anti-squeal shims if required.
- Reattach the caliper and torque the bolts to manufacturer specifications (typically 20-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if needed)

Inspection:
- Check the rotors for scoring or warping using a straightedge.
Replacement:
- If necessary, remove the rotor by unscrewing the retaining screws and slide it off.
- Install new rotors, ensuring they are clean and free of oil.
- Torque the retaining screws according to specifications.

5. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).
Pump the brake pedal to restore pressure before testing the brakes.
