Removing Hydraulic Unit

Information 

• When fitting the hydraulic connections, the electric plug connections on the control units must remain connected as long as possible. 
• This prevents the plug connections on the hydraulic unit or inside the connector from being splashed with brake fluid or water. 
• Before disconnecting the cable plug from the hydraulic unit, wipe the connector to remove any dampness. Apply suitable protection to the connectors if necessary. 
• Brake fluid on electrical contacts (even thinned brake fluid) causes corrosion and may result in faults in the system. 
• The brake lines must not be bent in the hydraulic unit area. 
• Clean the connection points of the brake lines, but not with cleaning agents. 
• Rinse off emerging brake fluid thoroughly with water.
