Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Loosen wheel lug nuts slightly before lifting the vehicle.

2. Raise Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the brake components.

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Inspect the brake pads for thickness; replace if below 3mm.
Replacement:
- If necessary, remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly aligned.

4. Inspect and Replace Brake Rotors (if needed)

Check the rotors for damage; replace if excessively worn or damaged.
Remove the rotor by unscrewing the retaining screws or bolts.
Install new rotors, ensuring they are tightened to the manufacturer’s torque specifications (generally around 85-90 ft-lbs).

5. Reassemble Brake Components

Reinstall the caliper over the new brake pads and rotor.
Tighten caliper bolts to manufacturer specifications (typically 25-30 ft-lbs).
Reinstall the wheel and lug nuts, tightening them in a star pattern.

6. Final Checks

Lower the vehicle and remove jack stands.
Tighten the lug nuts to the specified torque (usually 75-80 ft-lbs).
Pump the brake pedal several times to ensure proper brake pad contact.
