Front brake lock-up

Hi. I just replaced front hubs, rotors, calipers, and pads on my '86 F-150 4x4. After putting everything back together and bleeding the front brakes (master cylinder has separate resevoirs so I assume I don't need to do the back), the front brakes became stuck on after a couple of drives in it (both sides). What kinds of things could be causing this? Could a poor bleed job do this (I'm definitely a beginner)?

Any ideas/suggestions/things to try welcomed.

Thanks,
Tim

Front brake lock-up

Check your push rod(between the master cylinder and vacuum boster).
Sounds like the piston in the master cylinder is not coming all the way back, after releasing the brakes.
Some rods are adjustable.
