Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, protective gloves, safety goggles.
Park the vehicle on a level surface and engage the parking brake.
Allow the vehicle to cool if it has been driven recently.

2. Raise the Vehicle

Using a jack, lift the front or rear of the F-150 (as applicable).
Secure the vehicle with jack stands to ensure safety.

3. Remove Wheel

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

4. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set and slide the caliper off the rotor.
- Check brake pad thickness; if less than 1/8 inch, replace.
- Remove old brake pads and clean the caliper bracket with brake cleaner.
- Install new brake pads into the caliper bracket.
- Reinstall the caliper over the new pads and secure it with bolts.

5. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- If rotors are scored or worn beyond specification, remove them by unscrewing the rotor retaining screws (if applicable).
- Install new rotors, ensuring they are clean and free of oil.
- Torque the rotor screws to the manufacturer's specifications (usually around 10-15 ft-lbs).

6. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground using the jack.
Use the torque wrench to tighten the lug nuts to the manufacturer's specifications (typically around 100-150 ft-lbs).

7. Final Check

Pump the brake pedal a few times to ensure proper pad seating.
Check brake fluid level and top off if necessary.
