ITEM	:	HYDRAULIC DUAL CIRCUIT BRAKE SYSTEM
MODELS	:	BS-HD1-T		HDC BRAKE SYSTEM
		BS-HD2-T		HDC BRAKE SYSTEM WITH FAULT
		BS-HDG		SET OF 2 PRESSURE GAUGES INSTALLED IN LINE

This demonstration board shows the design and function of a hydraulic dual circuit brake system. The demonstration board is designed so that the brake system is fully operational. When the brake pedal is depressed, the hydraulic circuit is activated which controls the drum and disc brake. While the brakes are in operation the brake light is illuminated. 

All parts are original automotive components which are mounted onto a demonstration board. The major components included are the twin (Tandem) master cylinder, brake pedal unit, brake light, brake light activator switch, one disc brake unit, one drum brake unit, hand brake lever, all necessary cabling and hydraulic fluid lines. The demonstration board features a silk screened schematic of the major brake components and hydraulic operational function. 

The drum brake system has been sectioned to show internal parts where possible without affecting the operational characteristics. An optional fault valve can be included which simulated the action of leak in a brake line. Optional set of two pressure gauges are available to show braking fluid pressures. They are installed  in the front and rear lines (option BS-HDG).
