Return pump
Return pump |
The pump unit is only activated when an outlet valve is opened and it returns excess brake to the master cylinder.
The pressure of the returning brake fluid is decided by the pressure in the master cylinder that is in turn proportional to the force applied to the brake pedal.
The pump unit capacity is approx. 250 bars, a pressure sufficient for all anticipated braking situations.
The hydraulic pump and electric motor can only be changed together with the valve block as a complete unit.
