Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a level surface and secure it with wheel chocks.
  • Wear safety glasses and gloves.
2. Check and Refill Brake Fluid
  • Remove the master cylinder cap and inspect the brake fluid level.
  • If low, top off with the appropriate brake fluid (DOT 4 for Skoda Octavia).
  • Replace the cap securely.
3. Inspect Brake Lines and Components
  • Raise the vehicle using a jack and secure it with jack stands.
  • Visually inspect all brake lines for signs of wear, cracks, or leaks.
  • Check the calipers and wheel cylinders for fluid leakage.
  • If leaks are found, replace the damaged components.
4. Bleed the Brake System
  • Attach a clear hose to the bleeder valve on the brake caliper.
  • Have an assistant press the brake pedal while you open the bleeder valve to release air and old fluid.
  • Close the valve before releasing the pedal.
  • Repeat until no air bubbles are present in the fluid.
  • Ensure the brake fluid reservoir remains full during the process.
5. Inspect and Replace Brake Pads/Rotor if Necessary
  • Remove the wheel to access the brake assembly.
  • Measure the thickness of the brake pads; replace if they are below the minimum specification (usually 3mm).
  • Check the rotor for grooves or warping; replace if necessary.
6. Test Drive
  • After repairs, take the vehicle for a test drive to ensure proper brake function.
  • Pay attention to the brake pedal feel and effectiveness during the drive.
