Repeated engagement of ABS, will likely ruin your unit though.
Race cars typically do NOT have ABS, and their drivers must sense when their tires at any of the four corners are about to approach the limits of breaking prior to onset of lockup, and slowly back off of the brakes (that is, unless that is what is desired i.e. drifting / rally, employing the E-brake).

Thanks for the thorough reply but why on the part in bold?
