Solution

1. Preparation

Ensure the vehicle is parked on a flat surface with the engine off.
Gather tools and parts required for the repair.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the front or rear of the F-150, depending on which brakes are being serviced.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Using a socket set, loosen and remove the lug nuts from the wheel.
Take off the wheel to access the brake assembly.

4. Inspect and Replace Brake Pads

Remove the caliper bolts with a socket wrench.
Carefully slide the caliper off the rotor and support it using a bungee cord (do not let it hang on the brake line).
Inspect the brake pads for wear; if they are worn down to the backing plate, replace them.
Remove the old brake pads and install new ones, ensuring they are properly seated in the caliper bracket.

5. Inspect and Replace Brake Rotors

If the rotors are scored or damaged, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install new rotors, making sure they are clean and free of any protective coating.
Torque the rotor retaining screws to the manufacturer’s specifications (typically around 7-9 lb-ft).

6. Reassemble

Position the caliper back over the new brake pads and rotor.
Reinstall the caliper bolts, tightening them to the manufacturer’s specifications (usually around 20-30 lb-ft).
Reattach the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
Torque the lug nuts to the manufacturer’s specifications (typically 75-100 lb-ft).
