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.
