my Skoda Octavia NFL (2020-Present) has a brake fluid leak, what should I do?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is off.
• Wear safety goggles and gloves to protect against brake fluid.

2. Check Brake Fluid Level

• Open the hood and locate the brake fluid reservoir.
• Remove the cap and check the fluid level. If low, top off with the recommended brake fluid (DOT 4 or as specified in the owner’s manual).

3. Identify and Repair the Leak

A. Brake Lines and Hoses

• Tools Required: Wrench set, brake line wrench
• Inspect all brake lines and hoses for cracks or wear.
• If a leak is found, replace the damaged line or hose:
  1. Use the brake line wrench to disconnect the line from the fittings.
  2. Replace with a new brake line or hose, ensuring it is properly routed and secured.
  3. Torque the fittings to the manufacturer’s specifications.

B. Brake Calipers

• Tools Required: Socket set, brake cleaner
• Inspect brake calipers for fluid seepage.
• If leaking, replace the caliper:
  1. Remove the wheel to access the caliper.
  2. Disconnect the brake line from the caliper using a wrench.
  3. Unbolt the caliper from the bracket and remove it.
  4. Install the new caliper and torque bolts to specification.
  5. Reconnect the brake line and ensure it is leak-free.

C. Master Cylinder

• Tools Required: Socket set, brake fluid
• Inspect the master cylinder for leaks:
  1. Remove the master cylinder from the brake booster.
  2. Replace any damaged seals or the entire master cylinder if needed.
  3. Reinstall and bleed the brake system to remove air.

4. Bleed the Brake System

• Tools Required: Brake bleeder kit
• After repairs, bleed the brake system to remove any air:
  1. Start with the wheel farthest from the master cylinder.
  2. Connect a brake bleeder kit and have an assistant pump the brake pedal.
  3. Open the bleeder valve and allow fluid to flow until there are no bubbles.
  4. Close the valve and repeat for each wheel.
