Lockheed 11 inch brake drum
I am surmising that the diametral limit for reboring (to correct an out-of-round drum) is 11.080 inch, which allows for a further .040 inch of wear, before a service limit of 11.120 inch is reached. I have not found any reference to the maximum allowable wear limit of this brake drum in any Bristol workshop manual. I suppose I am asking if a drum that has reached 11.120 inch ID which is otherwise in very good condition, can still be used with oversized brake linings. I would be pleased to hear from anyone who knows better. Thanks, vincent
