SD-1.12 Drum Brake Apparatus
This apparatus has been developed specifically for Motor Vehicle Mechanics and Motor Vehicle Technicians Courses
This apparatus has been developed specifically for Motor Vehicle Mechanics and Motor Vehicle Technicians Courses. It provides a means of demonstrating the difference in braking torque between leading (Primary) and trailing (Secondary) shoe braking systems and the effect on the braking systems and the effect on the braking torque of the various combinations of leading and trailing shoes. When the two shoes are linked together, the self energising action can be demonstrated.
The apparatus is suitable for use in the laboratory and may be used by the Students to carry out simple experiments to investigate the relationship between actuating forces and the braking torques and for the determination of the co-efficient of friction between the brake lining and the drum.
Two shoes with short brake linings are provided, additional shoes with full linings (SD1:12a) are available should these be required. For more advanced work, a special shoe may be supplied, fitted with an adjustable lining (SD1:12b); this enables the Student to investigate the effect on the braking torque when the pressure point on the brake shoe is displaced relative to the pivot point.
The apparatus is self contained and may be wall mounted or fitted to the Universal Bench Mounted Frame (Ref SD1:10).
