Rolls-Royce Ltd., DERBY. For the attention of W.A.Robotham Esq. Dear Mr. Robotham, In reply to your letter of Nov. 14th., we must apologise for having misunderstood your question regarding shoe bedding as altered by brake adjustment. We thought it was the altered bedding of the shoe ends or rollers on the wedge which was concerning you. Your point is now appreciated, however, and we can only say that we have never found the alteration in shoe contact, due to adjusting these brakes, to have any noticeable effect on their action when driving the Car. Presumably this is due to a combination of drum distortion, (which is fairly considerable on our Cars), shoe distortion, and the fact that shift of shoe contact towards the fulcrum point gives increased leverage, which may, to some extent, compensate for the loss of servo action on the leading shoe. Yours sincerely, THE ROVER COMPANY LIMITED. M C Wilks Technical Department. | ||
