Cut section unit of Hydraulic brake unit four wheel type Technical Specifications: SPECIFICATION: Cut Section Unit of Hydraulic Brake System (Four-Wheel Type) The model represents a complete hydraulic braking system of a four-wheeled vehicle, designed to demonstrate the principles, construction, and operation of both disc and drum brake mechanisms. The setup uses actual automotive components, sectioned and assembled on a display frame to facilitate practical understanding of the hydraulic circuit and braking dynamics. System Description: The unit illustrates the working of a conventional hydraulic brake system, showing the transmission of hydraulic pressure from the master cylinder to the wheel cylinders during brake application. The combination of front disc and rear drum brakes provides a comprehensive study of both systems within a single model. Technical Specifications: o Fabricated using original automotive brake components, sectioned to display internal construction and functional details. o Mounted on a robust mild steel frame with painted finish for durability and corrosion resistance. o Vacuum assisted hydraulic brake system. The vacuum assisted master cylinder will be connected to a vacuum pump to create vacuum and to understand the effect of vacuum assist on the brake system. o One set of Vaccum assisted Master Cylinder – sectioned to show the piston and fluid displacement mechanism. o And one set will be used for working of the brake system, where fluid can be filled into brake fluid reservoir o Brake Pedal Assembly – to manually operate the hydraulic circuit. o Two Front Hubs with Disc and Caliper Assemblies – for demonstration of disc brake operation. o Two Rear Hubs with Drum and Wheel Cylinder Assemblies – for demonstration of drum brake operation. o One side of the disc and caliper, Drum and wheel cylinder will be sectioned to show the internal details and other set will be made working. o All major parts are color-coded and labeled for easy identification and teaching. o The model will be provided with Colour printed circuit diagram/Parts diagram.
