my Volkswagen Tiguan's brake pedal goes to the floor what should I check

Solution

1. Preparation

• Gather necessary tools and materials.
• Ensure the vehicle is on a level surface and securely supported on jack stands.
• Wear safety glasses and gloves.

2. Inspect and Replace Brake Fluid

• Tools Required: Brake fluid, funnel, clean rags.
• Check the brake fluid level in the master cylinder reservoir; if low, top off with the recommended brake fluid.
• Clean any spilled fluid immediately as it can damage paint.

3. Identify and Repair Leaks

• Tools Required: Brake line wrench, replacement brake lines or fittings if needed.
• Inspect all brake lines and connections. If a leak is found, replace the damaged line or fitting.
• After replacing, bleed the brake system to remove air.

4. Inspect Brake Components

• Tools Required: Socket set, torque wrench.
• Remove the wheel and inspect the brake pads and rotors for wear. Replace if necessary.
• Ensure brake calipers are functioning correctly and not seized.

5. Check Brake Booster

• Tools Required: Hand-held vacuum pump.
• Test the brake booster by applying vacuum to the booster check valve. If it holds vacuum, it is functioning; if not, replace the brake booster.
