front brakes binding when moving forward, what can the problem be?

binding, as in, please describe a bit further, and perhaps some history on service that has been done recently., Please reread the question, and realize, you know what you are thinking, you have to let us know... I do want to help, but need a bit of description, thanks

With it being an 82 model and you just replaced slave cylinders. I would check the rubber hoses that go to each wheel. These tend to collapse or fall apart on the inside of the hose with age and specially if they have been moved around a bit. This would cause the fluid not to bleed off cylinder as it is suppose to. A way to check is to apply and release brake if wheel is still in a bind after releasing brake pedal loosen brake line fitting at cylinder to release the pressure. If wheel then turns freely it is most likely the rubber hose that is bad. Hope this helps.

Found no play in master cilinder, Reset and seems to operate now
