Stop in for a cup of coffee

No heat the bolt/nut or I do bleaders on brakes that are old. Get it hot with a propane torch, then put a birthday candle on it works the best to melt in the wax on the hot bolt. it creeps in and lubricates the threads. Will break free then. A old school machinist showed me it in the 80's. Seriously works. Never had a bleader I could not break loose, and they suck!
