my Ford F-150 14th Generation (2021-2024) has poor braking performance what’s wrong

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure vehicle is parked on a level surface and secure with wheel chocks.
• Wear safety goggles and gloves.

2. Brake Fluid Inspection

• Tools Required: Brake fluid tester, clean rags.
• Check the brake fluid level in the master cylinder reservoir.
• If fluid is low, top up with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
• Inspect fluid condition; if it appears contaminated, proceed to flush the system.

3. Brake Pad and Rotor Replacement

• Tools Required: Socket set, torque wrench, brake caliper tool.
• Loosen wheel lug nuts and lift the vehicle with a jack. Secure with jack stands.
• Remove the wheel to access the brake assembly.
• Unbolt the brake caliper and carefully slide it off the rotor.
• Remove old brake pads and inspect the rotor for scoring or warping.
• If necessary, replace the rotors and install new brake pads.
• Reattach the caliper and torque bolts to the manufacturer's specifications (usually around 23-37 lb-ft).

4. Brake Bleed Procedure

• Tools Required: Brake bleeder kit, clear tubing, catch container.
• Start with the wheel farthest from the master cylinder.
• Attach the tubing to the bleeder screw and open it slightly while a helper presses the brake pedal.
• Allow old fluid and air to escape until clean fluid appears, then close the bleeder screw.
• Repeat for all wheels until no air bubbles are observed.

5. Final Checks

• Reinstall the wheel and lug nuts, tightening to the manufacturer's specified torque (typically 150-160 lb-ft).
• Lower the vehicle and pump the brake pedal until it feels firm.
• Test drive the vehicle at low speed to ensure braking performance is restored.
