Have completed putting NOS brake shoes on my 38 and the last one (as always) is giving me problems getting the drum on. In looking at the wedge (78-2041), one side has a bevel that goes from top to bottom and the other side only has a partial bevel (slope) making it a steeper incline. When placing the wedge into the adjustment hole, does it make a difference which direction the two different sides face? I have both adjustments on the backer plate cleaned and lubricated and have tried everything. Having taken it apart several times, I noticed the sides of the wedge are different. I tried insertion both ways and it didn't help my problem but thought I would still ask the question.

The "green book" shows the adjusting wedge for 37-38 cable brakes with sides of equal length, and a flat on one side. When assembling, the wedge should be turned to allow the shoes to be retracted as far as possible. If all the other drums went on easily, it is possible that that one or both of the remaining shoes are incorrect. Compare them to determine if that is the case. One of the problems we have encountered with NOS parts is that they are mixed with the wrong ones, or the parts don't match the box. Very slight differences create a big problem.

Thanks for the information. I'm checking/matching parts but have yet determined what the problem is. The old shoes and new ones look identical matched side by side. Have taken a brief break for the holiday and hoping tomorrow will bring me some answers. Thanks again for your info on the wedges.
