My left front brake caliper hasn't been releasing, so I put another one on today, still won't release though. Answers anybody?

Im having the exact same problem on my 78 scottsdale 2wd, 1/2ton. Ive replaced the rubber left front brake line, the old one you couldnt blow air thru, and that seemed to work for a day, then the problem came back. The rotor gets very hot! Truck will hardly go its so locked up. cant spin the wheel by hand when its jacked up either.when u drive if you let go of the wheel it will pull u into the left ditch lol.. Yesterday I replaced the master cylinder, it was leaking anyway. Im wondering if the brake lines collapsed somewhere else, or if my caliper is ruined from the high heat that made it lockup..?? OR can it be the proportioning valve stopped up? or bad?

ANYONE OUT THERE PLEASE HELP BEFORE I JUST GO and


Thanks! Ill keep everyone posted!

try a new brake hose first those trucks are bad about the hoses failing.

Well I already changed that brake line for that caliper, and that seemed to work a little better, but then it got worse than it ever was.. I guess I will take off the caliper and then see if I can spin the wheel in the air, if not then wouldnt it have to be my wheel bearing locked? Thanks!
