Simple ASR systems have usually only access to the brake. Since the mechanical components are present already by the anti-skid system (ABS), the ASR is a software and a hardware extension of the ABS and can each drive wheel individually brake. Such an interference is necessary only for the wheels, which are propelled. The too fast wheel is braked thereby and the other wheel receives thereby more from the drive moment. The brake interference takes place thereby without the co-operation of the driver. The ABS is changed over for it with one additionally transfer valve by the normal brake enterprise to ASR enterprise. The scavenger pump of the ABS sucks in from the master brake cylinder brake fluid and produces the ASR system pressure. An active ASR regulation has an unfavorable effect during longer travels particularly in the Offroadbreich: the brake disks or - drums can become very hot, without one ever braked.
