Charge Pump

The charge pump is installed between the master cylinder and the brake fluid reservoir. During DSC controlled regulations that involve brake intervention, the charge pump ensures that the required volume of fluid is available for the hydraulic unit.

When activated, the charge pump draws fluid from the reservoir and delivers it to the master cylinder at a pressure of 10 Bar.
