A brake disc is mounted into a sturdy frame which must be mounted vertically. A single shaft runs through the brake disc and the wall bracket supports. A cord pulley mounts to the shaft onto which is mounted a cord terminating in a load hanger.
Two bell crank levers are mounted either side of the brake disc. Through the load hanger and calibrated weights the leverage load is applied to the brake disc and the parameters of braking force, braking torque, normal force can be assessed. All load hangers, and calibrated weights are supplied with the apparatus. The rotational angle of movement of the disc wheel can be viewed using the external protractor.
Different brake pad materials can be tested as well as their radial position on the brake disc.
A comprehensive instruction manual for lecturer and student, giving full details on apparatus assembly and operation as well as example results. All necessary assembly and operational tools are provided.
