| To RHC.{R. H. Coverley - Production Engineer} +206 Hs{Lord Ernest Hives - Chair}/AFM.{Anthony F. Martindale}2/KW.20.3.35. Bentley 1-B-IV. We want to make some brake drum temperature measurements on this car, and for this purpose we require it to be fitted with steel shoes. Will you therefore please fit the steel shoes to the rear footbrake (only) that you have taken out of 5-B-IV. The brass rivets securing the lining must be flush with the surface of contact with the drum. The one rivet in the main wrapping shoe (N.S.) nearest but one to the tipping shoe and farthest from the carrier plate should have a hole drilled in it .100" dia. This hole to be drilled from the inside of the shoe towards the drum, but must not quite reach the latter. This is admittedly a very delicate operation, but no doubt you will be able to manage it as before. Hs{Lord Ernest Hives - Chair}/A.F.Martindale. | ||
