-2- Rm{William Robotham - Chief Engineer}/AFMR/R.SL.3.37. We attach a print to this memo showing a tool Ford's use to stretch the brake lining while it is being rivetted on. Even if the progress Committee agree at once to alter the detailed drawings of shoes so as to give this stretch to the Ferodo, some time must elapse before the new pieces get on production, and in the meantime our brake shoes will probably continue to have a gap between them and the Ferodo. A scheme used by Rovers to get them out of the same difficulty was to coat the shoe with Petman's cement before rivetting the lining on. This produces an excellent solid job, and we have used it in the Experimental Department when working on brake squeaks. It is messy to use, and the shoe has to be scraped before re-lining. The chief reason for the universal insistence on getting the liner rivetted hard down on the shoe is that squeaks are said to occur if it is not. Rm{William Robotham - Chief Engineer}/AFM.{Anthony F.
