Removing Brake Master Cylinder

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 

Brake fluid - even thinned brake fluid - causes corrosion on electric contacts, thereby impairing functions.

1. Have suitable stoppers ready for closing off the connection openings.
2. Place suitable material underneath to collect emerging brake fluid, e.g. clean, absorbent cloths.
3. Disconnect brake lines -1 and 2-  on the brake master cylinder.
