my Skoda Octavia NFL (2020-Present) brake pedal goes all the way to the floor

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and engage the parking brake.
• Wear safety goggles and gloves.

2. Inspect and Top Off Brake Fluid

• Open the hood and locate the master cylinder.
• Remove the cap and check the brake fluid level.
  • Tools Required: None specific
• If low, top off with the appropriate brake fluid (DOT 3 or DOT 4, depending on the manufacturer specifications).

3. Inspect Brake Lines and Components

• Visually inspect all brake lines, hoses, and connections for any signs of leakage or damage.
• Check the brake calipers for leaks or fluid accumulation.
  • Tools Required: Flashlight
• If any leaks are found, replace the damaged lines or components as necessary.

4. Bleed the Brake System

• Begin at the wheel farthest from the master cylinder (usually the right rear), and work towards the nearest.
• Use a brake bleeder kit or a helper to press the brake pedal while you open and close the bleeder screw on each caliper.
  • Tools Required: Brake bleeder kit, wrench
• Continue until no air bubbles appear in the fluid.

5. Inspect Brake Pads and Rotors

• Remove the wheel to access the brake caliper.
• Check the thickness of the brake pads and condition of the rotors.
• Replace any worn or damaged components as needed.
  • Tools Required: Socket set, torque wrench
  • Torque Values: Refer to manufacturer specifications for caliper and wheel lug nut torque.

6. Final Checks and Assembly

• Reassemble any components that were removed, ensuring all bolts are torqued to specifications.
• Replace the wheel and lower the vehicle.
• Conduct a test of the brake pedal to ensure it feels firm and responsive.
