Abstract:
1. A master brake cylinder with opposing pistons that provides dual or tandem systems that are completely separate and individual, in a common body with a solid fixed dividing wall, comprising: a longitudinally floating main cylinder body with single open bores at opposite ends and a common solid closed dividing wall; two piston assemblies with sealing cups or poppets which slidingly work within the bores of the cylinders and when acted upon by an external push-rod force produce hydraulic fluid pressure and displacement for the actuation of brake calipers or drum brakes, so connected to each individual hydraulic system; a plurality of springs means positioned within or without of the cylinder bore to return the said pistons to their release positions; a retaining mechanism for retaining the pistons within the bores; an outer carrier mechanism to provide support for the brake cylinder with opposing pistons and to provide a reaction location for application of the opposed secondary piston to slide within its bore.
