Bailey - Chief Engineer} With reference to N.Sch.4798, being the Design Dept's. scheme for aluminium brake drums and reversed camshaft operation (to prevent jaggers). This layout of necessity reduces the proportion of front braking by a small amount, which will increase the minimum stopping distance of the car. We can restore the front braking by lengthening the centre front equaliser lever G.53076 from 1.720" to 1.900" as in RA.136. Will you please arrange to fit these levers to every car fitted with N.Sch.4798 - this includes E.R. Hall's racing car B-35-AN. We have not increased the proportion of front braking owing to CX{Major Len W. Cox - Advertising Manager}'s complaint of front wheels locking on greasy London streets, but we are working on a scheme to overcome this trouble. Ha/A.F.Martindale. | ||
