Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, socket set, torque wrench, caliper tool, safety glasses, gloves.
Raise the vehicle and secure it on jack stands.
Remove the wheel to access the brake assembly.

2. Inspect and Replace Brake Pads

Remove Caliper:
- Use a socket wrench to remove the caliper bolts.
- Carefully slide the caliper off the rotor and support it (do not let it hang by the brake line).
Inspect Brake Pads:
- Check for uneven wear; if one pad is significantly thinner, it should be replaced.
- Measure the remaining pad thickness.
Replace Brake Pads:
- If uneven wear is noted, remove old pads from the caliper bracket.
- Install new brake pads ensuring they are compatible with the F-150's specifications.
Reassemble Caliper:
- Compress the caliper piston using a caliper tool to make room for the new pads.
- Slide the caliper back over the new pads and secure it with the caliper bolts.
- Torque bolts to the manufacturer's specifications (typically around 25-35 ft-lbs).

3. Inspect and Replace Brake Rotors (if necessary)

Remove Rotors:
- If the rotors are warped or damaged, remove them after taking off the caliper.
- Unscrew any retaining screws and slide the rotor off the hub.
Install New Rotors:
- Clean the new rotor surfaces with brake cleaner to remove any protective oil.
- Slide the new rotor onto the hub and secure it with screws.

4. Final Setup

Reinstall the wheel and lower the vehicle.
Pump the brake pedal a few times to seat the pads against the rotor.
