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

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
• Disconnect the battery to avoid any electrical issues during repairs.

2. Identify and Isolate the Leak

• Brake Fluid Reservoir Inspection:

  • Remove the cap and visually inspect for cracks.
  • If damaged, replace the reservoir.

• Brake Line Inspection:

  • Trace brake lines from the master cylinder to the wheels.
  • Look for corrosion, frayed lines, or wet spots.
  • Replace any damaged brake lines with new ones.

• Caliper and Wheel Cylinder Inspection:

  • Remove the wheel to access the brake caliper.
  • Inspect caliper seals for any signs of fluid leakage.
  • If leaking, replace the caliper as a unit.

• Master Cylinder Inspection:

  • Remove the master cylinder mounting bolts.
  • Inspect the base for leaks; if present, replace the master cylinder.

3. Replace Damaged Components

• Brake Line Replacement:

  • Use a line cutter to remove the faulty section.
  • Install the new brake line and secure with appropriate fittings.
  • Bleed the brake system after installation.

• Caliper Replacement:

  • Remove the caliper mounting bolts and detach the caliper.
  • Install the new caliper and torque the bolts to manufacturer specifications.
  • Connect the brake line to the new caliper.

• Master Cylinder Replacement:

  • Remove the old master cylinder and install the new unit.
  • Tighten the bolts to the specified torque.
  • Reconnect the brake lines and bleed the system.
