Solution
1. Preparation
  • Gather necessary tools and safety equipment.
  • Ensure the vehicle is on a flat surface and secure with wheel chocks.
  • Disconnect the negative battery terminal for safety.
2. Inspect and Replace Brake Fluid
  • Tools Required: Brake fluid, funnel, rags
  • Remove the master cylinder cap and inspect the brake fluid level.
  • If low, top off with the appropriate brake fluid (DOT 4 for most Skoda models).
  • Check for contamination; if fluid is dark or dirty, proceed to replace it.
3. Inspect and Repair Brake Lines
  • Tools Required: Wrench set, brake line flare tool
  • Visually inspect brake lines for any signs of wear, corrosion, or leaks.
  • If a leak is found, replace affected sections of the brake line using the wrench and flare tool.
  • Ensure all connections are secure and leak-free.
4. Test and Replace Brake Booster (if necessary)
  • Tools Required: Hand-held vacuum gauge, socket set
  • Connect the vacuum gauge to the brake booster and check for proper vacuum levels (should be around 18-22 inHg).
  • If vacuum is insufficient, inspect the check valve for blockages or replace the brake booster.
  • To replace, detach the brake lines, remove mounting bolts, and install a new booster.
5. Reassemble and Recheck
  • Reattach the master cylinder cap and reconnect the negative battery terminal.
  • Bleed the brake system to remove any air that may have entered during repairs.
  • Test the brake pedal for firmness and ensure it operates smoothly.
