A control method is intended for controlling an antiskid braking system for a four-wheel-drive automobile in which the front and rear wheel sides are connected by a drive system. The control method includes a step of simultaneously reducing braking pressures on two rear wheels in accordance with the select-low principle when at least one of the rear wheels tends to lock. The step includes a process for reducing the braking pressure on that front wheel which is situated on the same side as the selected rear wheel determined in accordance with the select-low principle at the same time with the braking pressures on the rear wheels.
