Charlie, Yes the castings were very rough. I used a Dremmel to clean up the round half holes. I also had to do some grinding to get the brakes to fit on the backing plates[axel ends] . I replaces the cam bushings, cams and had to use my disk sander to take down some material from the lineings. Did not over do the lineing clean up for fear of taking to much off the rivets. Installed the new style seals and added some larger washers to hold the linings in place better on the backing plates. There is not much holding them on. I put the springs on the back side of the pads to kinda hold the pads in a bit. I used the gray high strength RTV gasket maker to seal the holes for the sleeves and applied a small amount to the end of the housing to get a good seal aginst the housing and the new seal. Put in new sleeves , packed the bearings good and peened the bearing pins to tighten them up a bit. The new brakes will need to wear in a bit right now there are rather tight, [draging]. But I think they will run in after a little running. The instructions with the seals say to seal the 3/8 hole for the sleeve dimple with a freezeout plug that they supplied but I opted to use the RTV that gives me a better seal and can be removed easily.
