Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Raise Vehicle

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

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Inspect the pads for wear; if less than 1/8 inch thick, replace.
Replace Brake Pads:
- Remove old pads from caliper bracket.
- Install new pads (ensure they are compatible with your F-150 model).
- Reassemble the caliper over the new pads and secure bolts to manufacturer specifications.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for grooves or uneven wear.
Replace Rotors:
- Remove the caliper bracket holding the rotor.
- Slide the rotor off the hub; if stuck, gently tap with a rubber mallet.
- Install new rotors, ensuring they are aligned properly.
- Reattach the caliper bracket and torque to manufacturer specifications.

5. Reassemble and Lower Vehicle

Reinstall wheels and torque lug nuts.
Lower the vehicle back to the ground.

6. Test Brakes

Pump the brake pedal to seat the pads.
Test drive the vehicle at low speeds to confirm noise is resolved.
