| Daimler side Brake steel does more on N. side than S. side. Radley can get it hair thin. Seems to be something in this phenomenon. Lower leverage plenty low enough now.

[/RED TEXT] Wor{Arthur Wormald - General Works Manager} to Mr Swift (Functions Std Harry) on 27-10-14 (124) no a/p must any more present brake part matt be m/o/d or fitted on new car after this week. Of much [RED TEXT] looked on that current brake work is for use in testing only. [/RED TEXT] CJ Wor{Arthur Wormald - General Works Manager}/Mer (TC) Ref Mr Williamson's chassis 13-11-14 (125) extract from letter of 7-11-14. I'm perfectly satisfied with the brakes on my car & cannot say how these could very well be improved. I've not tried all brakes on the latest chassis fitted up rather fancy. This may induce standing under certain condition. I think the latest method is a great improvement, constructionally as it relieves the transmission parts of the braking wear & tear. Mr Williamson's car will of course be fitted with the v latest type of DRB containing all the recent mods & improvements. | ||
