Abstract

Refinements in alarm apparatus for split-fluid pressure brake systems, of the type comprising, a brake light controlled by a first switching device operated in response to compression by at least one of the two independent secondary or auxiliary systems of the brake system, and a fault signal device controlled by a second switch device activated in response to movement in the opposite direction to the normal position of a movable piston hermetically sliding in a bore, to define two fluid chambers therein opposite connected to the two independent secondary or auxiliary brake systems, respectively, characterized in that said first switch device is actuated by a sensitive mobile piston device, on the one hand to the pressure of the fluid in one of said fluid chambers and, on the other hand, to an abnormal displacement of said mobile piston towards the inside said first fluid chamber as a result of a failure in the secondary or auxiliary brake system connected to it.
