What should I do here? 36 mod 51 brake

[farmboy]

I have seals ordered for both sides of the rear axle, the right side has signs of oil seepage but the brake shoes were fine. The left side is a different story, oil all over the place including the shoes. Do you think I can get these cleaned up enough to stop properly or put on new shoes? I'm not hauling loads in the ole beauty when it's done so thinking clean um up good and go with it? Depends if oil has soaked into them I guess? Thanks for any advice Bret
