Abstract
A braking system of the kind which comprises, for each front axle and each rear axle, at least one servo-operated control valve actuated by an anti-locking circuit which comprises a monitoring part and a control part, the electrical supply of the former being regulated by a safety switch controlled by the latter. According to the invention, the safety switch linked to the front axle is in series with the safety switch linked to the rear axle and is downstream thereof in relation to the corresponding current source. This de-activates the anti-locking circuit of the front axle in the event of failure of the anti-locking circuit of the rear axle, thus minimizing the possibility of locking of the rear wheels only during braking.
