Pressure Drop (Release)/Regulation Intervention





Hydraulic pressure in the brake caliper is released by the outlet valve and returns to the inlet side of the pump/master cylinder reservoir.

1. The inlet valve remains closed.
2. The outlet valve opens
3. The separator valve remains
4. The pump continues to run.





ASC+T Regulation will be switched off by:

1. Brake Application
2. Low system pressure. The pressure switch monitors system pressure and will switch ASC+T off if the low pressure threshold (80 BAR) is reached.
