Removing brake booster
Note:
^
During assembly work on hydraulic connections, the electrical plug connections on the hydraulic unit must always be connected. This prevents the
plug connections on the hydraulic unit and the inside of the connectors being splashed with brake fluid or water.
^
Damp connectors must be wiped dry before disconnection.
^
Brake fluid on electrical contacts (even thinned brake fluid) leads to corrosion and may cause faults in the system.
