my Skoda Octavia is leaking brake fluid, where could it be coming from?

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and securely supported with jack stands.
• Wear safety gloves and goggles.

2. Locate the Leak

• Sub-step 1: Start with a visual inspection of the brake fluid reservoir. If it’s cracked, replace it.
• Sub-step 2: Trace the brake lines and hoses along their entire length for any signs of leakage. If damaged, proceed to the next step.

3. Replace Damaged Brake Lines or Hoses

• Sub-step 1: If a brake line is found to be leaking, use a line wrench to disconnect the damaged line at both ends.
• Sub-step 2: Install a new brake line, ensuring it is properly routed and secured.
• Sub-step 3: If a rubber hose is leaking, remove it from the caliper and the hard line using a hose clamp tool, and replace it with a new one.

4. Repair or Replace Brake Calipers

• Sub-step 1: If a caliper is leaking, use a wrench to remove the caliper from the bracket.
• Sub-step 2: Inspect the caliper seals and pistons; replace the caliper if the seals are damaged.
• Sub-step 3: Reinstall the new or serviced caliper and ensure it is torqued to manufacturer specifications.

5. Inspect and Replace the Master Cylinder

• Sub-step 1: If fluid is leaking from the master cylinder, unbolt it from the brake booster.
• Sub-step 2: Replace it with a new unit if the leak persists after checking seals.
• Sub-step 3: Reconnect the brake lines and bleed the brake system.
