The Disc Brake Apparatus has been designedspecifically for Motor Vehicle Courses and may be used effectively forclassroom demonstrations. It may also be used by the student in the laboratoryto carry out simple experiments to investigate the relationship between the normalforce acting on the brake pads and the braking torque. The brake pads arelocated on bell crank levers to which the load hangers may be attached. Aspecial load beam is provided for use when carrying out experiments with twobrake pads. The supporting shafts are suitably drilled and pins provided so thatthe bell crank levers may be located in a number of radial positions. Byattaching suitable masses to a cord wrapped round the pulley on the disc shaft,the braking torque may be determined. This apparatus may be considered complementaryto the Drum Brake Apparatus and may be wall mounted or fitted to the UniversalBench Mounting Frame.
