Abstract
An anti-skid system for vehicle wheel brakes, in which signals for varying the brake pressure are obtained from the rotational behaviour of the vehicle wheels includes a test circuit which, when a signal indicating a tendency of the wheels to lock appears, initiates for at least one wheel brake a test in which the excessively braked wheel goes into a high degree of slip. The test circuit maintains the brake pressure substantially constant during the test and by monitoring said at least one wheel during a retardation phase establishes whether the vehicle wheel is running on a surface with a coeffcient of friction which rises again with increasing of slip from a higher value of slip onwards, as shown in the Figure, and renders the anti-skid control ineffective when such a coefficient of friction is ascertained.
