Rear Brake Problem

[Car'n'Guitars]

Okay I need help getting the rear brake lines off my truck to be replaced. My problem is it is so rusted I can't get the end pieces to unbolt from the part where they go into the drums. I don't really know what to do with it. The truck has basically new internal drum parts on it before it was parked but the lines are rusted junk. So has anyone had a similar problem and know how to resolve it? Also I can get pictures if needed.

You might just have to cut them, remove the wheel cylinders, and turn them out while the cylinder is in a vise. If you do it that way, try to use brass vise pads so you don't tear up the cylinders. Better yet, just get new cylinders. For my 1 ton dually they were only $9.
You can try using heat, but you would probably have to replace the cylinders after that anyway.

Yeah I was hoping I wouldn't have to replace any internal brake parts on the drum but if I have to I guess I will. I'd hate to because the only thing that really needs replaced are the lines.

If it's a half ton, wheel cylinders are dirt cheap, probably less than the lines. Swapping is simple, pull the drum, a couple bolts for the cylinder, usually can just spread the shoes enough ot get the new ones in. That way you don't have to fight the rsuty bleeder either.

If it's been sitting for any lenght of time the cylinders are probably pitted and will start leaking anyway.
But if you dont want to chage them, cut the line off at the nut and use a 6 point socket on them.
