why does my Volkswagen Golf MK7 (2015-2019) brake pedal go to the floor?

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is on a flat surface and the parking brake is engaged.
• Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Brake Fluid

• Tools Required: Brake fluid, funnel, clean cloth
• Inspect brake fluid for contamination or low levels.
• If fluid is low, top it up with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
• Clean any spilled fluid immediately, as it can damage paint and surfaces.

3. Inspect Brake Lines and Components

• Tools Required: Wrench set, flashlight
• Visually inspect all brake lines for signs of wear or leaks.
• Tighten any loose connections and replace corroded or damaged lines.
• Check brake calipers and wheel cylinders for leaks and ensure they are functioning properly.

4. Bleed Brake System

• Tools Required: Brake bleeder kit, clear tubing
• Start with the brake farthest from the master cylinder (usually the right rear).
• Attach the tubing to the bleeder valve and open it slightly while an assistant presses the brake pedal.
• Close the valve before the pedal is released to avoid air intake.
• Repeat until clear fluid without bubbles flows through.
• Continue bleeding in the order: right rear, left rear, right front, left front.

5. Replace Worn Brake Components

• Tools Required: Socket set, torque wrench
• Remove wheels to access brake components.
• Replace any worn brake pads or rotors as necessary.
• Ensure all components are installed according to manufacturer specifications and torque values.
