my Skoda Octavia's brake fluid is leaking what could be the cause

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Place wheel chocks behind the rear wheels for safety.

2. Inspect and Identify the Leak

• Tools Required: Flashlight, wrench set
• Visually inspect the entire brake system for leaks.
• Tighten any loose connections in the brake lines.
• If the leak source is identified, proceed to the next step.

3. Replace Faulty Components

• Tools Required: Wrench set, brake line repair kit or replacement parts
• Sub-steps:
  1. If the brake fluid reservoir is damaged, remove it by disconnecting the fluid lines and electrical connectors.
  2. If brake lines are corroded, cut out the damaged section and replace it with new brake line tubing, ensuring proper fittings are used.
  3. If the brake calipers or wheel cylinders are leaking, remove the affected caliper/wheel cylinder and replace it with a new unit.
  4. For a leaking master cylinder, disconnect the brake lines, remove the master cylinder, and install a new one.

4. Refill Brake Fluid

• Tools Required: Brake fluid (DOT 4 or as specified), funnel
• Refill the brake fluid reservoir with the appropriate fluid.
• Ensure there are no air bubbles in the system by bleeding the brakes if necessary.

5. Final Installation and Checks

• Reattach any components that were removed during the repair.
• Check for proper tightness and ensure there are no visible leaks.
• Dispose of any old brake fluid and materials according to local regulations.
