Structure and inner electrical connection

The reed contact has the effect of a switch. If the reed contact is activated, ground to the DSC control unit is interrupted.

In the brake fluid expansion tank, a residual capacity is retained for the other brake circuit (leakage protection) in the event of a brake circuit leakage. In addition, a volume for the clutch control is integrated into the brake fluid expansion tank (not I01).
