Installing Brake Master Cylinder

Information 

• During assembly work at hydraulic connections, all electric plug connections in the connection point area must always be connected. This prevents the inside of the plug connections from being splashed with brake fluid or water. 
• Clean any plug connections that have become dirty or damp during removal and assembly work using a lint-free cloth. 
• Brake fluid on electrical contacts (even thinned brake fluid) causes corrosion and may result in faults in the system. 
• Remove any escaping brake fluid immediately; rinse with water and dry thoroughly if necessary.
