why does my Ford F-150 14th Generation (2021-2024) brake pedal feel soft and go to the floor

Solution

1. Preparation

• Gather tools and materials: brake fluid, torque wrench, brake bleeder kit, socket set, and safety goggles.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect and Address Brake Fluid Level

• Sub-steps:
  • Open the hood and locate the brake master cylinder.
  • Check the brake fluid level; if low, top it off with the recommended brake fluid type (DOT 3 or DOT 4).
  • If fluid is low, inspect for leaks and proceed with bleeding the brakes.

3. Brake Line and Caliper Inspection

• Sub-steps:
  • Visually inspect brake lines for any cracks, corrosion, or leaks.
  • Examine brake calipers for signs of fluid seepage or damage.
  • If leaks are found, replace damaged lines or calipers as necessary.

4. Bleed the Brake System

• Sub-steps:
  • Attach a brake bleeder kit to the bleeder valve of the furthest brake caliper from the master cylinder.
  • Have an assistant pump the brake pedal several times and hold it down.
  • Open the bleeder valve to release air and fluid, then close it before the assistant releases the pedal.
  • Repeat this process for each wheel, moving from the furthest to the closest to the master cylinder.
  • Check fluid levels frequently and top off as needed.

5. Master Cylinder Replacement (if necessary)

• Sub-steps:
  • If the master cylinder is found to be faulty, remove the brake lines connected to it using a wrench.
  • Unbolt the master cylinder from its mount and replace it with a new unit.
  • Reattach brake lines and ensure all connections are tight.
  • Bleed the brake system again to remove any air.
