how to fix my Volkswagen Tiguan First Generation (2007-2018) if the brakes are soft

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and engage the parking brake.
• Place wheel chocks behind the rear wheels.
• Wear safety glasses and gloves.

2. Check Brake Fluid

• Tools Required: Brake fluid tester or gauge.
• Remove the master cylinder cap and check fluid level.
• If low, top off with the appropriate brake fluid (DOT 4 for most VW models).

3. Inspect and Repair Brake Lines

• Tools Required: Wrench set, brake line bender (if replacing lines).
• Visually inspect brake lines and hoses for signs of wear or leaks.
• If leaks are found, replace the damaged lines or hoses as necessary.
  • Disconnect the damaged line using a wrench.
  • Install the new line, ensuring all connections are tight and leak-free.

4. Bleed the Brake System

• Tools Required: Brake bleeder kit, clear tubing.
• Start from the wheel farthest from the master cylinder (usually the right rear).
  • Attach the clear tubing to the bleeder valve.
  • Open the valve and have an assistant press the brake pedal several times.
  • Close the valve before they release the pedal.
  • Repeat until no air bubbles are visible in the fluid.
• Move to the next wheel and repeat the process until all four are bled.

5. Inspect Brake Pads and Rotors

• Tools Required: Jack, jack stands, lug wrench.
• Remove the wheel and visually inspect the brake pads and rotors.
• If pads are worn down to the indicator or rotors are scored, replace them.
  • Remove caliper bolts and slide the caliper off.
  • Replace the brake pads and reassemble the caliper.
  • Reinstall the wheel and lower the vehicle.
