rear brake cylinder vs sheared bleeder valve dilemma

[RustyPile]

^^^ What he said.. Your picture clearly shows bleeder valves aren't the only rusted beyond safe use items.. "Cool" isn't even a close consideration here.. Get rid of those wheel cylinders and brake lines.. Go through the complete brake system, replacing any and all safety related items.. The $400 I spent last year on the brakes on my truck is the best money I've spent.. The truck stops on a dime and that's the coolest part of my truck....
