(11) Front brake liners to be eased off at the extremities of the shoes as instructed by Gry.{Shadwell Grylls} (12) New pivot pins to be fitted. (13) We understand that this is a 4° transverse lean front axle, in which case we should like a standard axle of the strengthened type to be fitted at the same time as the new pivot pins.
