| No. 2 In the case of the Wolseley method great care is required in fitting correctly in the first instance, while new blocks fitted at any time may easily be found to bear only perhaps on the heel or nose, thus giving rise to unsatisfactory working. Of course the attachment being carried on the gear box is much more rigid and in this respect it is the better arrangement, but while safe enough for a little car I do not like the idea of carrying brake stresses through the aluminium gear box in cars of any size. With regard to cost, I should not imagine that there can be any marked difference between the two methods of anchoring, except the cost of the extra link and pin required by the R.{Sir Henry Royce} R.{Sir Henry Royce} arrangement, which is probably compensated for by the greater accuracy required by the Wolseley method. Taking the brake and actuation as a whole I should estimate the Wolseley to be the cheaper as it contains considerably fewer parts. H.C. Clark R.R. S32v (100M) (WB{Mr Brazier/Mr Bell} 312) 2-40 W.L.
