Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Remove Wheel

Loosen lug nuts using a socket set.
Lift the vehicle using a jack and secure with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads and Rotors

Inspection:
- Remove the caliper by unbolting it from the bracket.
- Inspect brake pads for thickness; replace if below manufacturer's minimum specification (usually 3mm).
- Check rotors for scoring and warping.
Replacement:
- If rotors are warped or below minimum thickness, replace them.
- Clean the rotor surface with brake cleaner.
- Install new rotors, ensuring proper orientation.
- Apply anti-seize to the hub mating surface to prevent future corrosion.

4. Reinstall Caliper and Brake Pads

Reinstall the brake pads in the caliper bracket.
Reattach the caliper over the new pads and torque bolts to manufacturer specifications (typically 20-40 ft-lbs).
Ensure the caliper slides freely.

5. Reassemble Wheel and Lower Vehicle

Reinstall wheel and hand-tighten lug nuts.
Lower the vehicle and torque lug nuts to the manufacturer's specifications (typically 100-150 ft-lbs).
Remove wheel chocks and ensure the parking brake is released.
