The Stovebolt Site Forums The Shop Area Driveline rear brake drum

Need rear brake drum's 1950 3100.I had drum turn,when first brought truck was a mistake. Six bolt pattern.Was looking on line.most show drum for 1951.This is why left rear keep hanging up.wheel cylinder move to far out,causing it to hang up.

You may be right, but unless the brake drum has been turned really way oversize, (like into the time to scrap it oversize) It isn't likely the cylinder will extend too far. I would be more inclined to check the cylinder for rust beyond the former limits of travel, perhaps causing it to hang up. Check the brake shoes, if the friction material on the end of the shoes (narrow dimension) isn't beveled a little bit, take a coarse file and put a bevel there. Most of the new ones you will get already have the bevel there, (but if the ones you have don't, then probably you won't notice) Avoiding breathing the dust of course. I have ran into this problem a couple of times, The first time I about pulled my hair out, given it was on a piece of equipment we desperately needed to work.

Thank about the bevel .The cylinder are new,but adjusted to max.I count the thread on the adjustment screw.One full turn on screw is fifty thousand.I'am at seven thread both side of cylinder . all most 3/8 of inch each side
