Volkswagen Golf MK7 (2015-2019) brake pedal feels soft, how do I fix it?

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the parking brake is engaged.
• Wear safety goggles and gloves.

2. Check and Refill Brake Fluid

• Tools Required: Brake fluid, funnel.
• Locate the brake fluid reservoir under the hood.
• Inspect the fluid level; if low, add the recommended brake fluid type (usually DOT 4 for VW).
• Check for contamination in the fluid; if the fluid is dark or cloudy, proceed to flush the system.

3. Inspect for Leaks

• Tools Required: Flashlight, brake cleaner.
• Visually inspect all brake lines, hoses, and connections for signs of leakage.
• If leaks are found, replace the damaged components.

4. Bleed the Brake System

• Tools Required: Brake bleeder kit, wrench, clear tubing.
• Begin with the brake furthest from the master cylinder (usually the passenger side rear).
• Attach the clear tube to the bleeder valve on the brake caliper.
• Have an assistant press the brake pedal, then open the bleeder valve to release air and fluid. Close the valve before the pedal reaches the floor.
• Repeat until no air bubbles are visible, then move to the next brake in the order: driver’s side rear, passenger side front, driver’s side front.
• Ensure the brake fluid reservoir remains full during the process.

5. Check Brake Components

• Tools Required: Socket set, torque wrench.
• Remove the wheel to access the brake caliper and rotor.
• Inspect brake pads for thickness and even wear; replace if less than 3mm.
• Check the condition of the rotors; replace if warped or excessively worn.

6. Reassemble and Test

• Reinstall the wheel and torque to manufacturer specifications.
• Test the brake pedal feel; it should be firm and responsive.
• Perform a test drive to ensure proper braking performance.
