Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety glasses.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Raise the Vehicle

Use the jack to lift the front or rear of the F-150, depending on where the grinding noise originates.
Secure the vehicle on jack stands.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the braking components.

4. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts with a socket set and slide the caliper off the rotor.
- Inspect the brake pads for thickness; if the pads are worn down to less than 1/8 inch, replace them.
- If replacing, use brake cleaner to clean the caliper and rotor surface.
- Install new brake pads ensuring they are oriented correctly.

5. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- Check the rotors for grooves or significant wear; if damaged, replace them.
- Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
- Install new rotors, ensuring they are clean and free of debris.

6. Reassemble Braking Components

Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications.
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 manufacturer specifications.
