SD-1.25-Disc Brake Apparatus

The Disc Brake Apparatus has been designed specifically for Motor Vehicle Courses and may be used effectively for classroom demonstrations. It may also be used by the student in the laboratory to carry out simple experiments to investigate the relationship between the normal force acting on the brake pads and the braking torque.

The brake pads are located on bell crank levers to which the load hangers may be attached. A special load beam is provided for use when carrying out experiments with two brake pads. The supporting shafts are suitably drilled and pins provided so that the bell crank levers may be located in a number of radial positions.

By attaching suitable masses to a cord wrapped round the pulley on the disc shaft, the braking torque may be determined.
