An anti-skid brake control system has a brake pressure control unit for producing a release signal to trigger the release of brake pressure and a subsequent re-apply signal to trigger the re-application of brake pressure in successive brake pressure release/re-apply cycles; and a change-over control unit for producing a change-over signal to trigger a change from a first, rapid re-apply stage, in which brake pressure is re-applied rapidly, to a second, slow re-apply stage in which brake pressure is re-applied slowly, during the re-apply period of each cycle; the change-over control unit including a storing device responsive to the duration of the re-apply period in successive cycles so that the change-over point in each cycle is controlled in a manner dependent on the duration of the re-apply period in the preceding cycle, whereby the duration of the re-apply period is dynamically adjusted to assume a preset value. Preferably, the change-over point in each cycle is further controlled in a manner dependent on the duration of the brake release period of that cycle so that the duration of the brake release and brake re-apply periods change in same sense.
