my Skoda Octavia's brake pedal goes to the floor what should I check

Solution

1. Preparation

• Gather tools, including a socket set, brake fluid, a brake bleeder kit, and a wrench.
• Ensure the vehicle is on a level surface and securely supported with jack stands.

2. Check and Refill Brake Fluid

• Open the hood and locate the brake fluid reservoir.
• If low, carefully remove the cap and fill the reservoir with the appropriate brake fluid (DOT 4 recommended for Skoda).
• Replace the cap securely after refilling.

3. Inspect and Replace Damaged Components

• Brake Lines and Hoses:

  • Inspect each brake line and hose visually for cracks or signs of leakage.
  • If any damage is found, use a wrench to disconnect the damaged line and replace it with a new one, ensuring proper torque specifications (usually around 12-15 Nm for brake lines).

• Brake Calipers/Wheel Cylinders:

  • Remove the wheel to access the calipers.
  • Inspect for leaks; if found, remove the caliper using a socket set, replace it with a new one, and bleed the brakes afterward.

4. Bleed the Brake System

• Using a brake bleeder kit, start at the wheel furthest from the master cylinder (usually the rear passenger side).
• Attach the bleeder kit to the brake bleeder valve on the caliper, open the valve, and pump the brake pedal until no air bubbles are observed in the fluid.
• Repeat for each wheel, moving closer to the master cylinder.

5. Test the Brake System

• After bleeding, check the brake pedal feel; it should be firm.
• Test drive the vehicle at low speeds to ensure brakes engage properly.
