Friction Braking Systems.


PB179352

Publication Date 1968
Page Count 183
Abstract The report is a description and evaluation of the development and testing of rapid transit friction brake systems. Seven brake systems, representing various control and force application designs, were chosen for installation on the test vehicles: Pneumatic tread; Electrical tread; Electro-pneumatic tread; Pneumatic disc; Electric disc; Hydraulic disc; and Hydraulic tread. Each system was tested and evaluated with respect to its control, accuracy, linearity, efficiency, and expected life, in addition to its general performance characteristics. (Author)
