<p>A brake testing device (100) evaluates the condition of a disk (102) having a disk axis (106) and first and second disk surfaces (108, 110). The device (100) has two gauges (112, 124), each having a sensing element (114, 126) for measuring the position of one of the disk surfaces (108, 110) along a line parallel to the disk axis (106). The gauges (112, 124) generate signals corresponding to the measured positions of the disk surfaces (108, 110). The gauges (112, 124) are secured with respect to each other so as to measure along parallel lines, and are positioned by the device (100) to measure the disk surfaces (108, 110) at points equidistant from the disk axis (106). Gauges (218, 230) can be employed which allow testing a disk (202) surrounded by a wheel (208) and a dust shield (206). The device (100) may be part of a system (750) which processes the signals to determine the thickness and the lateral run-out of the disk (102), and which may also compare these values to manufacturer-specified standards.</p> |
