Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks for safety.
Safety Warning: Allow the vehicle to cool down if recently driven.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle.
Secure with jack stands for safety.
Remove the front wheels using a socket set.

3. Inspect and Remove Brake Components

Inspect Brake Rotors:
- Use a dial indicator to measure rotor runout. Replace if warped beyond specifications (typically 0.002 inches).
Remove Brake Calipers:
- Unbolt the caliper mounting bracket using a socket set.
- Hang the caliper using a bungee cord to avoid stress on the brake line.
Remove Brake Pads:
- Slide out brake pads from the caliper bracket for inspection.

4. Replace or Resurface Rotors

If rotors are warped, either replace them or have them resurfaced if within specifications.
Installation:
- If replacing, install new rotors and torque the retaining bolts to the manufacturer's specifications (typically 75-85 ft-lbs).

5. Install New Brake Pads

Apply brake grease to the backing of the new pads to prevent squeaking.
Install the new pads into the caliper bracket.
Reattach the caliper, ensuring it is secured properly.

6. Reassemble and Lower the Vehicle

Reinstall the wheels and torque the lug nuts to the specified torque (typically 90-100 ft-lbs).
Lower the vehicle from the jack stands and remove wheel chocks.

7. Test the Brake System

Pump the brake pedal to ensure proper engagement.
Perform a test drive to confirm the issue has been resolved.
