ABSTRACT:
A hydraulic brake system for a vehicle having a traction control system, in which at least one self-aspirating pump, pressure fluid can be aspirated through an intake line and a charging valve and can be fed into a brake line leading to at least one wheel brake. A pressure limiting valve that diverts pressure fluid from the brake line to the intake line is also provided. To speed up the braking intervention, the pump is briefly turned on and the charging valve is opened when the vehicle is started, to carry away any gas bubbles that might be located between the charging valve and the pump. This averts the possibility that the compression of gas bubbles that might be present at the onset of traction control could cause the pump to pump less pressure fluid. The method can be employed in hydraulic brake systems of motor vehicles with traction control systems.
