They're front drums, John, and he's already gotten them off by using my suggestion to unbolt the wheel cylinders. Now we're discussing wheel cylinder rebuilding techniques in case new/rebuilt cylinders aren't available. I ended up making new pistons for the big GMC that Ed Pruss left with me for a while- - - -new wheel cylinders were available from NAPA, but they were about $100.00 each, and 4 of them were needed just to fix the front brakes!
