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 in the connectors inside from being splashed with brake fluid or water .
Any damp connector must be wiped dry before being disconnected from the connector on the hydraulic unit. If necessary, provide the connector with a suitable protector .
Brake fluid on electrical contacts (even thinned brake fluid) leads to corrosion and may cause faults in the system .
The brake lines must not be bent in the area of the hydraulic unit .
Clean the interfacing points of the brake lines, but not with cleaning agents .
Rinse off any brake fluid emerging thoroughly with water .

Place a suitable cloth underneath to catch any emerging brake fluid.
Disconnect brake lines -1- .
