<p>A vehicle hydraulic braking installation includes a main master-cylinder 1 operated by the driver's brake pedal with or without servo-assistance and an additional master-cylinder 13 which is operated when the driver releases the accelerator pedal. The additional master-cylinder is connected to the braking circuit only through the main master-cylinder. As soon as the main master-cylinder begins to be operated, the main master-cylinder cuts off any communication between the additional master-cylinder and the braking circuit.</p> |
