Abstract

A vehicle brake system (2) with a brake pressure source (3) which can be controlled by means of a pedal (4), with wheel brakes (8, 9, 10, 11) and with a device which is arranged between the brake pressure source (3) and these wheel brakes (8, 9, 10, 11) and is designed at least to limit drive slip at drivable vehicle wheels is proposed. In order to produce brake pressure for limiting drive slip, an easily reachable handle (6) or a second pedal by means of which the brake pressure source (3) can be activated when the drive slip is to be limited is assigned to the brake pressure source (3) in addition to the pedal (4). The proposed vehicle brake system (2) can be used advantageously in vehicles whose drivable wheels are connected to a drive motor (engine) via a friction clutch which can be controlled by pedal. The arrangement of the handle (6) permits brake pressure to be produced manually during the actuation of a clutch pedal and an accelerator pedal such as is necessary when starting. The use of two brake pedals is advantageous in vehicles with automatic gears. If drive slip is to be limited, a signal transmitter (33) issues a request for the actuation of the handle (6). <IMAGE>
