Document Type and Number:
WIPO Patent Application WO2003011667
Kind Code:
A8
Abstract:
A Master Brake Cylinder (10) with Opposing Pistons (15, 16) providing dual or tandem hydraulic systems that are completely separate and individual, comprising a longitudinally floating main cylinder body (11) with single open bores at opposite ends and a common solid closed dividing wall (17), two piston assemblies (15, 16) when acted upon by an external push-rod force (26) produce hydraulic fluid pressure and displacement for the actuation of brake calipers and/or drum brakes, so connected to each individual hydraulic system, a plurality of springs means positioned within or without of the cylinder bores to return the pistons (15, 16) to their release positions, a retaining mechanism for retaining the pistons (15, 16) within their bores, an outer carrier mechanism (12, 13) to provide support for the brake cylinder (10) and a reaction location for application of the opposed secondary piston (16) to slide within its bore.
