What would cause back brakes on a 1985 f-150 to Stick, Have to put in reverse to release??

bad springs. Get a new hardware kit, only 15 dollars, easy fix.

apparently this happens when you first get in the vehicle. Check the parking brake cables for damage.

might also have a leaking axle seal. gear oil causes the pads to swell. you'll have to rip the drums off and see whats going on.
