why does my Ford F-150 12th Generation (2009-2014) shudder when braking

Solution

1. Preparation

• Park the vehicle on a flat surface and engage the parking brake.
• Gather all necessary tools and parts.
• Ensure you have proper safety equipment (gloves, safety glasses).

2. Remove Wheel

• Sub-steps:
  1. Loosen the lug nuts using a lug wrench while the wheel is still on the ground.
  2. Lift the vehicle using a jack and secure it with jack stands.
  3. Remove the lug nuts completely and take off the wheel.
• Tools Required: Lug wrench, floor jack, jack stands.

3. Inspect and Replace Brake Components

• Sub-steps:
  1. Inspect brake pads; replace if worn below the recommended thickness (usually 3mm).
  2. Check the brake rotors with a dial indicator; replace if warped beyond the manufacturer's specifications (typically more than 0.002 inches of runout).
  3. If necessary, remove the caliper by unbolting it from the bracket and support it without stretching the brake line.
  4. If rotors are to be replaced, unbolt them from the hub assembly and install the new rotors.
  5. Reinstall the caliper and ensure it is properly secured.
• Tools Required: Socket set, torque wrench, caliper tool, brake cleaner, new brake pads, new rotors (if necessary).

4. Reassemble and Torque

• Sub-steps:
  1. Reinstall the wheel and hand-tighten the lug nuts.
  2. Lower the vehicle from the jack stands and remove the jack.
  3. Torque the lug nuts to the manufacturer's specification (typically around 100-150 lb-ft).
• Tools Required: Torque wrench.
