The master cylinder for this vehicle is a composite design which contains a plastic reservoir and an aluminum body. This design is used in a diagonally
split system. One of the front and one of the diagonally opposite rear brakes are served by the primary piston. The opposite front and rear brakes are
served by the secondary piston.
The master cylinder incorporates the-functions of a standard dual master cylinder. The master cylinder has a fluid level switch and integral proportioner
valves. The proportioner valves are designed in order to provide a better front to rear braking balance during a heavy brake application.
