ABSTRACT:
A circuit configuration for an anti-lock brake system, which receives input from wheel sensors positioned on the driven wheels, comprises a monitoring circuit (7) which triggers a test cycle (duration T.sub.Test) when the two wheels of a driven axle signal instability for more than a predefined time span (T) during a control cycle. By way of the test cycle, braking pressure is introduced into the wheel brake of the instantaneously slower wheel (v.sub.1, v.sub.min -wheel) of the driven axle and the reaction of the driven wheels to the braking pressure delivered is assessed.
