ABSTRACT:
A brake system including a traction control apparatus having at least one pressure generator 35, which has a cylinder 60 for receiving and expelling brake fluid by means of a piston 60. The cylinder 60 is connected, with a valve 72 actuatable as a function of the motion of the piston 50, to a pressure course between the master brake cylinder and a wheel brake cylinder. To attain a short structural length, on the one hand, and a long stroke of the pressure generator on the other, the piston is embodied as a rod piston; it is connected to a coaxially extending hollow cylinder 40 that envelops the piston 50 in the cylinder 60; the hollow cylinder 40 is longitudinally guided and is provided with a racklike set of teeth 41 on its outside for the engagement of a motor drive mechanism 43 for driving the piston relative to the cylinder.
