Brake Chamber Nut Rusted On

I'm a diesel mechanic, so we have a lot of knuckle busters. I'm down here in Houston, and a tractor-trailer came in with a brake chamber problem. This driver runs north and south, encountering snow, salt, and a lot of rust. One of the nuts that holds the chamber on wouldn't move, so I got out the Kroil penetrant with silicone and sprayed the nut down, letting it soak in. I put the impact on it, and it freed the nut right up. Kroil penetrant/silicone is truly a life saver.

I won't use anything, but Kroil and when I have difficult issues with my car, as in recently have to pull a exhaust manifold, I gifted my mechanic a can which he said worked fantastic
