Braking system

The braking system is of the dual circuit hydraulic type with disc brakes at the front and drum brakes at the rear. A diagonally split dual circuit hydraulic system is employed in which each circuit operates one front and one diagonally opposite rear brake from a tandem master cylinder. Under normal conditions both circuits operate in unison; however, in the event of hydraulic failure in one circuit, full braking force will still be available at two wheels. A pressure regulating valve on Saloon and Estate models, and a light laden valve on Van models is incorporated in the rear brake hydraulic circuit. The valve regulates the pressure applied to each rear brake and reduces the possibility of the rear wheels locking under heavy braking.
