Removing Brake Booster

Information 

When carrying out work during which fluids can escape, leave electric plug connections to be disconnected locked and connected for as long as possible. This prevents fluid from getting onto electric contacts and causing corrosion.

Information 

Any escaping brake fluid must be removed immediately. Rinse contacts with water and dry them if necessary.

1. Have suitable aids ready to soak up emerging fluids and have stoppers ready for closing off the line connections.
2. Unscrew nuts on the brake booster -1-  .
