my Skoda Octavia’s brake pedal goes to the floor what does this mean

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
• Disconnect the battery negative terminal for safety.

2. Inspect and Replace Brake Fluid

• Tools Required: Brake fluid tester, fluid catch container
  • Open the brake fluid reservoir cap.
  • Use a brake fluid tester to check the fluid quality.
  • If contaminated or low, siphon out old brake fluid using a fluid catch container.
  • Refill with the manufacturer-recommended brake fluid (e.g., DOT 4).

3. Check and Repair Brake Lines

• Tools Required: Wrench set, pliers
  • Inspect all brake lines and hoses for any signs of corrosion or leaks.
  • Tighten any loose connections found during inspection.
  • Replace any damaged brake lines or hoses with new ones.

4. Inspect and Replace Brake Components

• Tools Required: Socket set, torque wrench
  • Remove the wheel to access the brake caliper and rotor.
  • Inspect the brake pads for wear; replace if they are below the minimum thickness.
  • Check the brake rotor for grooves or warping; replace if necessary.
  • Reassemble the braking system, ensuring all bolts are tightened to the manufacturer’s specifications.

5. Check and Replace Master Cylinder (if necessary)

• Tools Required: Socket set, brake fluid catch container
  • If leaks are found at the master cylinder, remove it from the brake booster.
  • Replace with a new master cylinder, ensuring all connections are secure.
  • Bleed the brake system to remove any air pockets.

6. Final Assembly and Testing

• Tools Required: Torque wrench
  • Reinstall the wheel and lower the vehicle.
  • Reconnect the battery terminal.
  • Pump the brake pedal to build pressure and check for firmness.
  • Test drive the vehicle at low speeds to confirm proper braking function.
