Title: Tandem master cylinders for hydraulic braking systems

Abstract: In a tandem master cylinder main and secondary pistons are interconnected by a rigid sleeve. One end of the sleeve is secured to one of the pistons, and an inwardly projecting lip or flange on the other end of the sleeve provides an abutment for a head on an axial stem extending from the other piston towards the said one piston. The head is axially slidable in the sleeve and is introduced into it through an opening in the wall of the sleeve, which opening is connected by a longitudinal slot to the end of the sleeve which is provided with the lip or flange.
