1. A master cylinder assembly comprising: a cylinder body having an inlet port and an outlet port, and defining a cylinder chamber adapted to communicate via the inlet port with a fluid reservoir and to hold hydraulic fluid supplied therefrom, the cylinder chamber including two or more pressure chambers each having a transfer port; a piston member fitted for slidable movement within the cylinder chamber, the piston member including two or more pistons received in respective pressure chambers, and being operable to move the pistons, in parallel, to thereby transfer hydraulic fluid held therein through the respective transfer ports; and a pressure valve assembly operable to selectively direct hydraulic fluid transferred through at least one transfer port out of the cylinder body through the outlet port, to establish a variable fluid output at the outlet port upon operation of the piston member.
