    Default Resurrecting Oily Brake Shoes

    I know that there has been some discussion in the past on this and I never really found a solid answer....I have pulled off several brake shoes from both my deuces that are oily and i had several so i just replaced them. I know the common word is to not use them but some have said the oil can be baked out and so forth. Does anyone have a solid experience on truly making them useable again? These that I have are mostly full thickness so i think it is worth trying.

    Don't want to throw money I don't have away.

    We used to just burn the oil out with a torch on big trucks, common sense has to be applied of course, too much heat can break down the friction material, especially when it is already soaked in oil, you will typically find however that not the entire shoe is soaked in oil or brake fluid, usually just the outer surface, and if so they should be salvageable .

    Heat enough all around to bubble the contamination out w/o destroying the material, done it, it works, there is typically no reason to throw away thick shoes that are mildly contaminated unless you are made of money .

    Yes you can sometimes get away with "burning" out the oil. It all depends on how much oil the shoes have absorbed. If they have had oil leaking on them for a long time then I would replace the shoes. The oil has gone through the whole shoe. Even burning it will not get rid of all the oil.
    Having worked in the trucking industry for decades I've seen many "tricks" to try and get rid of oil on brake shoes. Truth be told none of them can ever get rid of all the oil, including the "burning" out with a torch trick. Steam cleaning and degreasers along with torching can help with a new leak, but really never gets all the oil out either.
    So since oily brakes is not just a mechanical problem, but a "safety" and "liability" issue I would just bite the bullet and replace them. Of course if your life and the lives of those around you doesn't mean much to you, then by all means run the shoes.

    Well, for someone like me that tries to prepare for SHTF, having some mostly de-oiled brake shoes might be a good thing to keep around if none more are available...ever.
