why does my Ford F-150 shake when I brake

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Park the vehicle on a level surface and engage the parking brake.
• Wear safety gloves and goggles.

2. Raise the Vehicle

• Use a jack to lift the front of the vehicle.
• Secure the vehicle with jack stands for safety.
• Remove the front wheels using a lug wrench.

3. Inspect and Replace Brake Components

a. Inspect Brake Rotors

• Visually check for scoring, grooves, or warping.
• If warped, remove the caliper by unscrewing the caliper bolts and hang it using a bungee cord.
• Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off.
• Replace with new rotors if necessary. Ensure the new rotors are clean and free from oil.

b. Inspect Brake Pads

• Remove the brake pads from the caliper bracket.
• Check for uneven wear; replace if worn below specifications (usually 3mm).
• Install new brake pads, ensuring they are properly seated.

4. Reassemble Components

• Reattach the brake caliper over the new pads and rotor.
• Tighten caliper bolts to manufacturer specifications (typically 25-30 ft-lbs).
• Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Torque Wheels

• Carefully lower the vehicle off the jack stands.
• Use a torque wrench to tighten the lug nuts to the manufacturer’s specified torque (usually 80-100 ft-lbs).
