Abstract

In a boosted master cylinder assembly the booster output rod (38) is connected to the primary piston (23) of a tandem master cylinder (1) and a spring (39') in the booster (2) biases both the primary piston and the output rod rearwardly. A single stop in the form of an annular seal assembly (31) is engaged by the retracted primary piston to determine the retracted position of both the primary piston and the output rod so that no adjustment is required. A substantial part of the length of the master cylinder is located within the booster housing (4), and the master cylinder reservoir 81 is mounted on the booster housing.
