The brake master cylinder has an intermediate piston with integrated central valve, which means that the compensation bore in the intermediate piston brake circuit is no longer used. This function is assumed by the central valve.

The central valve prevents the primary cup seal of the thrust rod piston being damaged at the compensation bore due to pressure fluctuations which are produced by the ABS control processes during brake pressure build-up
