my Skoda Octavia NFL (2020-Present) has a warning for brake system failure what does it mean

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and engage the parking brake.
• Disconnect the battery to prevent electrical shorts and ensure safety.

2. Fluid and Component Inspection

• Brake Fluid Check

  • Remove the cap from the brake fluid reservoir.
  • Check fluid level; top up with the recommended brake fluid (DOT 4 for Skoda vehicles).

• Component Inspection

  • Remove the wheel to access the brake assembly.
  • Inspect brake pads for wear; replace if thickness is less than 3 mm.
  • Examine rotors for scoring or warping; resurface or replace if necessary.
  • Check caliper operation; ensure it moves freely.

3. Brake Line and Booster Check

• Brake Line Inspection

  • Inspect all brake lines for cracks, corrosion, or leaks.
  • Replace any damaged lines with OEM parts.

• Brake Booster Test

  • With the engine off, press the brake pedal several times to deplete vacuum.
  • Start the engine; the pedal should drop slightly indicating proper booster operation. If not, replace the brake booster.

4. Reassemble and Test

• Reinstall the wheel and torque lug nuts to the manufacturer’s specifications (typically 90 Nm).
• Reconnect the battery and start the vehicle.
• Test the brakes by applying them gently at low speed to ensure proper function.
