Abstract

A servo-assisted hydrodynamic braking system of the type in which brake pedal pressure is used to control a modulating valve which restricts an output line of a pump thereby increasing the pressure in the output line which is connected to the master cylinder of the braking system in such a way as to apply this increased pressure as a servo-assisting pressure, in which the master cylinder and modulating valve are made as a composite assembly and the pressure within the master cylinder part is used to control the modulating valve so that no direct mechanical interconnection between the brake pedal and the modulating valve is needed.
