why does my Volkswagen Golf Eighth Generation (2020-present) brake pedal feel soft

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Wear safety gloves and goggles for protection.

2. Inspect Brake Fluid Level

• Open the hood and locate the brake fluid reservoir.
• Check the fluid level against the minimum and maximum markings.
• If low, top off with the manufacturer's specified brake fluid (e.g., DOT 4).

3. Bleed the Brake System

• Tools Required: Brake bleeder kit, wrench, brake fluid.
• Start with the wheel furthest from the master cylinder (usually the rear passenger side).
• Have an assistant press the brake pedal while you open the bleeder valve on the brake caliper.
• Close the valve before the pedal reaches the floor and then have the assistant release the pedal.
• Repeat until no air bubbles appear in the fluid, then move to the next wheel.
• Ensure to keep the brake fluid reservoir filled during the process.

4. Inspect and Replace Brake Pads and Rotors (if necessary)

• Remove the wheel to access the brake components.
• Inspect the brake pads for thickness and condition; replace if worn beyond specifications (usually below 3mm).
• Check the rotors for warping or scoring; replace if necessary.
• Reassemble with new parts ensuring proper torque specifications are followed.

5. Check Brake Booster

• Inspect the vacuum line connected to the brake booster for leaks or damage.
• Replace the brake booster if it’s found to be malfunctioning.
