Y4612 In order to determine the effect of the thicker drums on brake squeaks, a steel band was shrunk on the outside of the drum of 14-EX. The drums were originally 3/16" thick, the bands were 3/16" thick. The nett result was that the brakes still squeaked. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
