Hi, I have a used Midland Ross and Bendix unit. The Bendix unit has a tear in the rubber boot and does not work. The Midland Ross unit is from a parts car and may also need to be rebuilt. Does anyone still make a rebuilding kit for either unit? I am somewhat afraid of buying one that is NOS because the rubber may be old and tear easy. The one I have in the car was rebuilt by Arrow, but I understand they are out of business. The push rod on the rebuilt unit was shorter than the previous one which makes the brake pedal go closer to the floor board, but it still works OK. Was there two or more lengths to the pushrods? It seems like there should be one length only? 300ly, Mark Lindahl '63 300 Conv.
