how to check the brake lines on my Ford F-150 13th Generation (2015-2020)

Solution

1. Preparation

• Tools Required:
  • Safety glasses
  • Mechanic's gloves
  • Flashlight
  • Wheel chocks
  • Jack and jack stands
• Ensure the vehicle is parked on a flat surface and the engine is off. Use wheel chocks to prevent rolling.

2. Raise the Vehicle

• Loosen the lug nuts on the front or rear wheels (depending on which brake lines you are inspecting) slightly while the vehicle is still on the ground.
• Use the jack to lift the vehicle and support it securely with jack stands.
• Remove the lug nuts and wheels for better access to the brake lines.

3. Inspect Brake Lines

• Visual Inspection:

  • Follow the brake lines from the master cylinder to the brake calipers or drums. Look for any visible signs of wear, cracking, or corrosion.

• Check Fittings and Connections:

  • Examine all fittings for tightness and look for any signs of fluid leakage. Pay attention to the areas where the lines connect to the brake calipers and master cylinder.

• Feel for Soft Spots:

  • Run your hand along the brake lines to check for soft or mushy spots, which could indicate internal damage or degradation.

4. Test for Leaks

• Fluid Check:

  • Check the brake fluid reservoir to ensure it is at the correct level. If it is low, inspect the brake lines for leaks more thoroughly.

• Bleed Test:

  • Pump the brake pedal several times and hold pressure. If the pedal sinks to the floor, there may be a leak in the lines.

5. Reassemble and Lower Vehicle

• Reinstall the wheels and lug nuts hand-tight.
• Lower the vehicle carefully and tighten the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs for F-150).
• Dispose of any waste fluid properly if brake fluid was found leaking.
