| - 3 - by any possible difference in the coefficient of friction between the driven plate and the lining and the driving plates and the lining. --------- [Handwritten] Suggest we should examine these before we issue standardisation sheet Bifurcated rivets have completed 20,000 miles on the front brakes of 19-G-IV and 12,000 miles on the clutch on the same car. We agree that they can go on production as outlined in Sft.{Mr Swift}8/BH.15.12.32 subject to the few alterations indicated in the foregoing. Will Hs.{Lord Ernest Hives - Chair} issue a standardization sheet for this. --------- With regard to the Phantom II Brake straps, we think that economy can be obtained without loss of efficiency by reducing the number of rivets. Will By.{R.W. Bailey - Chief Engineer} issue particulars (to be tested on the next 10,000 miles car) in which two thirds of the number of rivets are used. On the Bentley we agree that Bifurcated rivetting should be tried. Will By.{R.W. Bailey - Chief Engineer} please issue the necessary modifications experimentally. E/Lid.{A. J. Lidsey} | ||
