Solution

1. Preparation

Sub-steps:
- Park the vehicle on a level surface and engage the parking brake.
- Gather necessary tools and parts.
- Ensure wheel chocks are in place.
Tools Required: Socket set, jack and jack stands.

2. Remove the Wheel

Sub-steps:
- Loosen the lug nuts slightly while the vehicle is on the ground.
- Use a jack to lift the vehicle and secure it with jack stands.
- Fully remove the lug nuts and take off the wheel.
Tools Required: Lug wrench, jack, jack stands.

3. Inspect and Replace Brake Components

Sub-steps:
- Inspect the brake rotors for warping using a dial indicator. Replace if warped beyond specifications (usually over 0.002 inches).
- Check the brake pads for thickness; replace if below 1/4 inch.
- If rotors are not warped but have uneven wear, consider resurfacing them.
- Replace any worn or damaged brake calipers.
Tools Required: Dial indicator, brake pad gauge, rotor puller (if necessary).

4. Reassemble and Torque

Sub-steps:
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to manufacturer specifications (typically 80-100 ft-lbs for F-150).
Tools Required: Torque wrench.

5. Final Checks

Sub-steps:
- Test the brake system by performing a slow speed brake test in a safe area.
- Ensure no vibrations or noises persist after the brake replacement.
Tools Required: None.
