(same as 20/25) With 15% larger servo this can be :- 377 + 500S Arranged to give 45% front braking this becomes :- 377 + 200S to rear + 300 S to front All the levers in the servo braking remain to the original N.scheme giving 193 S and 304S. The direct lever G.100958 at present 2.000 is increased to 3.400. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} | ||
