Abstract

A master brake cylinder includes a unique mounting arrangement for securing thereof to a firewall of a vehicle and a particular porting arrangement. A cylinder sleeve includes a series of ports that cooperate with movement of the piston allowing for by-passing of the piston at one end position and then movement of the piston past the ports for brake actuation. Additionally a two stage pressure intensifier is provided that is in-line between a master brake cylinder and brake pistons. The intensifier also includes a by-pass position at one end of the movable piston having a differential area between a forward and a rear face of the piston.
