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

Solution

1. Preparation

• Gather tools: Socket set, brake fluid, brake bleeder kit, OBD-II scanner, floor jack, jack stands, and a container for catching brake fluid.
• Ensure the vehicle is on a level surface and the engine is off.

2. Inspect and Refill Brake Fluid

• Sub-step 1: Open the hood and locate the master cylinder reservoir.
• Sub-step 2: Check the fluid level. If it’s low, refill it with the manufacturer-recommended brake fluid (DOT 3 or DOT 4, as specified).
• Sub-step 3: Inspect for leaks around the reservoir cap and lines; if any leaks are found, replace the affected components.

3. Bleed Brake System

• Sub-step 1: Start at the wheel farthest from the master cylinder (right rear).
• Sub-step 2: Attach the brake bleeder kit to the bleeder valve on the brake caliper.
• Sub-step 3: Have an assistant press the brake pedal and hold it down.
• Sub-step 4: Open the bleeder valve to release fluid and air; close the valve before your assistant releases the brake pedal.
• Sub-step 5: Repeat this process until no air bubbles are visible in the fluid.
• Sub-step 6: Move to the next wheel (left rear, then right front, and finally left front), repeating the bleeding process.

4. Inspect and Replace Brake Components

• Sub-step 1: Remove the wheels to access the brake components.
• Sub-step 2: Inspect the brake pads for wear; replace if they are worn below the manufacturer’s specifications.
• Sub-step 3: Check the rotors for scoring or warping; replace if necessary.
• Sub-step 4: Reassemble the brakes and wheels, ensuring all components are torqued to the manufacturer’s specifications.
