Abstract
A brake testing apparatus and method are disclosed which utilize a hydraulic subsystem as a stroke-limiting memory unit and as a position-holding means during the brake test sequence. The hydraulic subsystem is designed for inclusion in a brake testing means which performs a series of analyzable brake tests using a controlled force application system which applies the brakes under different, but predetermined, conditions in a series of successive brake applications. The stroke measuring memory unit uses the hydraulic subsystem to measure the distance of one brake application stroke and limits the next brake application stroke to that distance. The position-holding means utilizes the hydraulic subsystem to retain a given brake-applying position of the testing apparatus for the length of time desired in certain brake applications in the testing series.
