Heh. Yesterday I was running out options on the wagon's rusted parking brake cable. Two days of soaking with Kroil. Hitting between each coil with a cold chisel. A litte acetone. Figured nothing left to lose. If I could just free it, that would be enough. Put tension on it, then heated the coils dull red where it had no flex. Shortly after was rewarded with a POP! Unfortunately it was the cable itself inside breaking. :( Must not have been much left of it.
