Solution

1. Preparation

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

2. Lift the Vehicle

Sub-steps:
- Use a jack to lift the front of the vehicle and secure with jack stands.
- Remove the front wheels with a socket set.

3. Inspect Brake Components

Sub-steps:
- Remove the brake caliper by unbolting it and suspend it with a wire to avoid stress on the brake line.
- Inspect brake pads for wear; replace if thickness is below specifications (typically 3mm).
- Check rotors for warping by measuring with a dial indicator. If warped, replace them.

4. Replace Brake Rotors (if necessary)

Sub-steps:
- Remove the old rotors by unscrewing any retaining screws.
- Clean the hub surface to ensure a flat seating for the new rotor.
- Install the new rotor, ensuring it is securely fastened.

5. Reassemble Braking System

Sub-steps:
- Reinstall the brake caliper over the new rotor and tighten bolts to the manufacturer’s torque specification (usually between 75-90 ft-lbs).
- Reinstall the wheel and lug nuts, tightening them in a star pattern to the manufacturer’s specification (usually around 76 ft-lbs).

6. Lower the Vehicle

Sub-steps:
- Remove jack stands and lower the vehicle back to the ground.
- Test the brake pedal for firmness before driving.
