In an antiskid system for vehicles, brake control apparatus for automatically controlling the application of braking pressure to the wheels including sensing means such as a tachogenerator for producing electrical signals which are analogues of wheel speed, means for differentiating the analogue signal transducer means producing signals indicative of vehicle deceleration, means for producing a reference signal having a value determined in accordance with vehicle deceleration, dual-mode integration means responsive to said analogue and reference signals to produce output signals representative of wheel speed when the integrator operates according to one mode and to produce output reference signals representative of vehicle speed and controlled by vehicle deceleration when the integrator operates according to the second mode, a first comparator device responsive to the differentiated signals and a second comparator device being responsive to signals from the first comparator device and the integration means to produce a control signal for the actuation of antilock control valve means to reapply the braking pressure whenever the wheel speed signal is equal in magnitude to the reference speed signal.
