RELATION OF WHEEL TREAD WEAR AND BRAKE SHOE WEAR

Brake shoe requirements on freight cars equipped with conventional brake rigging are not completely equitable at all shoe locations. Studies indicate that replacments of mated shoes on the same brake beam can vary from 8 percent on the inside beams to 13 percent on the outside beams. Four diagonal locations are found to have a shoe requirement approximately 55 percent, and the four mating positions 45 percent of total replacements. The unequal shoe wear adversely in so far as realizing uniformity of service life on the wheels in the four positions as well as on mated wheels at the respective locations. The pattern of wheel wear disclosed is not conductive to economy of car maintenance not to the best standard attainable in car utilization.
