The brake fluid in the vehicle can be displaced by the larger diameter piston in large volumes, but at low pressure. The valves are regulated in such a way that once a pressure level has been reached, at which the brakes friction surfaces are in line (filling pressure), the larger diameter piston is being gradually inhibited, allowing the smaller diameter piston to take over. Thus high brake pressures can be obtained without excessive efforts. For the reasons explained above, these master cylinders do not meter out a specific fluid volume, but a variable one, depending on the type of brake system, brake clearances, etc. FUNCTION SCHEME CONFRONT BETWEEN STEP BORE AND SINGLE DIAMETER The single diameter master cylinders are usually simple and cheap. The main advantages of the step bore master cylinders are a big displacement and the high braking pressures even without booster feeding. For this reason, they are much appreciated, as they enable to avoid the installation of hydraulic accumu- lators or other emergency devices working when the engine is off. In brake systems requiring a big displacement before starting to brake, they enable to reduce the filling stroke and to increase the working stroke. - cod. 010A-200704A-EN - 030.020 Total Displacement [cc] Min/Max Master Cylinder Ref.
