Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Lift Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on where the issue is suspected.
Secure with jack stands for safety.

3. Inspect and Replace Brake Components

A. Brake Rotors

Remove the wheel using a socket set.
Remove the caliper by unbolting it and support it with a wire to avoid strain on the brake line.
Inspect the rotor for warping using a dial indicator.
If warped, replace the rotor with a new one, ensuring it is properly torqued to the manufacturer's specifications (usually around 70-90 ft-lbs for F-150).

B. Brake Pads

Check the thickness of the brake pads; replace if they are worn down to 3mm or less.
Clean the caliper bracket and apply brake grease to the contact points of the new pads.
Install new pads ensuring they are seated properly.

4. Inspect Suspension and Wheel Bearings

Check all suspension components for play or damage; replace worn parts as necessary (e.g., ball joints or tie rods).
Spin the wheel hub to check for roughness indicating bad wheel bearings; replace if needed.

5. Reassemble and Lower Vehicle

Reattach the caliper and ensure all bolts are properly torqued.
Reinstall the wheel and torque lug nuts to manufacturer specifications (usually around 100-120 ft-lbs).
Lower the vehicle and remove jack stands.
