Skoda Octavia NFL (2020-Present) brake pedal goes to the floor why

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and secure.
• Disconnect the negative battery terminal for safety.

2. Check Brake Fluid Level

• Open the master cylinder reservoir cap.
• If the fluid is low, top it off with the manufacturer-recommended brake fluid (usually DOT 4).
• Inspect the reservoir for cracks or damages that may cause leaks.

3. Inspect Brake Lines and Components

• Visually inspect brake lines for rust, corrosion, or damage.
• Check all connections and fittings for signs of leakage.
• Tighten any loose fittings as necessary.

4. Replace Leaking Components

• If leaks are found in the brake lines, replace the damaged section using a flare tool to create proper connections.
• If the master cylinder is defective, remove it by unbolting it from the brake booster and disconnecting the brake lines.
• Install the new master cylinder, ensuring proper alignment and secure fittings.

5. Bleed the Brake System

• Reconnect the brake lines to the master cylinder.
• Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valves on each brake caliper to remove air from the lines.
• Ensure the brake fluid level remains sufficient during this process.

6. Final Checks

• Reconnect the negative battery terminal.
• Test the brake pedal for proper feel and function before driving.
• Inspect once more for any leaks around the components replaced.
