Brakes stickin after brake job

I'm facing a similar issue with Big O Tires, where they replaced my front and rear brake cylinders, shoes, everything, then decided to change the master cylinder, then the front brakes wouldn't let go after you stopped at a stop sign. Now the brake pedal travels about 3/4 of the way down before the brakes start grabbing. No leaks either, and I've been back and forth with them because they swear up and down they took the drums back apart and everything is just as it should be. This was after the cylinders they replaced popped again.

Hopefully you get yours resolved, but my belief is that the companies hire people who can do tires - and that's it.
