1979 Ford F250 V8 Four Wheel Drive Manual 187000 miles
I have a 79 f-250. I'm have problems with the front right brake locking up. I've changed the caliper and the rubber hose going to the steel line. Both front brakes are only a couple months old. This problem is only a couple weeks old. I'm still having the problem with just my front right brake locking up. Could this be my proportioning valve?
