Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Allow the vehicle to cool if it was recently driven.

2. Lift the Vehicle

Use a jack to lift the front of the F-150 and secure it with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Pads

Remove the brake caliper by loosening the caliper bolts.
Slide the caliper off the rotor and support it without stretching the brake line.
Remove the old brake pads from the caliper bracket.
Insert new brake pads into the bracket, ensuring proper orientation.

4. Check and Resurface/Replace Rotors

Remove the brake rotor from the hub. If warped, resurface or replace it.
If resurfacing, ensure it's within manufacturer specifications for thickness.
Install the rotor back onto the hub, securing it with the appropriate fasteners.

5. Reassemble Components

Reattach the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's torque specifications.
Reinstall the wheels and lower the vehicle.
