A motor vehicle brake control system having traction control and incorporating controller features and methods of operation which interrupt activation of the traction control system in conditions likely to develop excessive brake temperatures, exceed available brake pressure limitations, or other adverse brake conditions. This feature is provided by monitoring the behavior of the system, and based on known braking system characteristics, disabling the traction control when certain parameters are exceeded. The system provides these features without the need to directly measure brake temperature, brake system pressure or other physical parameters.
