We conducted a research on reducing weight under the spring of the Shinkansen rolling stock. As a way of reducing the weight, we developed a new brake disk made of Aluminum alloys instead of conventional steel. The conclusions are as follows. 1) A lining for the aluminum disc is newly developed. By softening the lining and by improving the contact surface condition of the lining, we were able to stabilize friction coefficient from the initial braking and also prevent temperature rise during braking. 2) The new hybrid brake disc using MMC for sliding surface and AC4CH for matrix was developed. The optimum thickness of the MMC was found to be 7mm from visual inspection and the shape measurement after testing. 3) The brake testing was performed using the new lining and the new brake disc in sets. We measured the friction coefficient, disc temperature, lining temperature and the amount of lining wear. We believe these data are useful in putting the new lining and brake disc into practical use in the future.
