It does sound like the brake hoses, I've had this problem more than once.
The hose is a double wall design, quite often the inner seperates from the outer. The inner hose collapse's and is pushed open by the forcing of fluid through it when the brakes are applied. Then when the brakes are released and there's an absents of pressure(fluid) the inner hose collapse's trapping some of the fluid on brake pad/ shoe side; making the brake stay engaged with the drum/ rotor.
You can confirm this by seeing if there's fluids under pressure at the bleeded valve. Just to remember, that this can last a couple of seconds to a couple of minutes, or longer.
