| -2- that if we fit a stop to the front equalizer shaft, the trouble which at present occurs when the swinging arm friction increases temporarily, is overcome. The stop itself requires cushioning with a piece of Ferodo and the attached sketch indicates the manner in which this has been carried out. Having silenced the servo, the noise of the brake pedal hitting its stop becomes very noticeable, but can easily be cured by a pad of Ferodo on the stop. We attach a report from G.S.H. on these stops and also on a dash pot which he tried out and which appears to be an almost complete solution to the trouble. We recommend that some scheme should be got out to reduce the noise of brake release. TMF/RM.{William Robotham - Chief Engineer} | ||
