Abstract

1,195,402. Brake indicators; pistons. M. L. FAY. 9 Oct., 1967, No. 46118/67. Headings F2E, F2F and F2T. A piston and cylinder device comprises: a piston 13 provided at one end with a primary resilient sealing member 16 and a secondary resilient sealing member 17, the two members defining an annular space 19; and a pressure operated switch 21 connected to an indicator (not shown) and communicating with space 19. Any leakage of fluid pressure past the member 16 causes the switch to close and operate the indicator. The arrangement may be applied to either the master or slave cylinders of a braking system.
