E.{Mr Elliott - Chief Engineer} XS-360 Hs{Lord Ernest Hives - Chair}/RM{William Robotham - Chief Engineer}3/BES1.3.33. BRAKE THUMPS Probably one of the worst complaints on the existing 20/25HP. is that of thumps in the brake. We are about to send a car on 10,000 miles, and on it we have no cure for brake thumps. On the other we have received a scheme from WW. for an oil dashpot which has, at least, a reasonable chance of being successful. We should very much like to make an effort to get this detailed and on 18-G-IV. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
