72 blazer brakes dragging

I just changed master cylinder to a new one. And put a used booster old one was rusty and leaked. Now my brakes drag after I drive for a few minuets. It's the fronts only because they were smoking. My brakes were perfect before this.

It's a factory 2wd 72. 307 original 3 on tree I swapped to 350th

Any help is appreciated thanks

Re: 72 blazer brakes dragging

I have this happen to me on 2 diff ol chevys.

Old or even new kinked interal brake hoses that couldnt be fixed w/o replacing.

Spec of dirt at the bottom of the MC (sys was new from wheel cyls to MC and everything in between so I dunno how it got in there...
