Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Lift and Secure the Vehicle

Use a hydraulic jack to lift the front of the F-150.
Place jack stands under the vehicle for safety.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the front wheel.

4. Inspect and Replace Brake Rotors

Inspect Rotors: Use a dial indicator to measure rotor runout. If warping exceeds manufacturer specifications (typically 0.002 inches), replace.
Remove Caliper:
- Unbolt the brake caliper using a socket.
- Hang it securely using a bungee cord to avoid stress on the brake line.
Remove Rotor:
- Unscrew any retaining screws if present and pull the rotor off the hub.
Install New Rotor:
- Clean the hub surface and install the new rotor, ensuring it sits flush.
- Secure any retaining screws.

5. Replace Brake Pads

Remove Old Pads: Slide out the old brake pads from the caliper bracket.
Install New Pads: Ensure the new pads are aligned correctly and clipped into place.
Reinstall Caliper: Bolt the caliper back into place, ensuring proper torque (typically around 25-35 ft-lbs).

6. Reassemble Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (typically 150 ft-lbs).

7. Test Brake System

Pump the brake pedal several times to seat the pads against the rotors before driving.
Conduct a test drive to ensure the issue is resolved.
