With any vehicle the brakes can stick on if left for some time.
It is caused by damp forming a film of rust on the discs or drums, drive a few miles braking gently now and again and the rust will be worn off by the shoes or pads and everything should be ok but do stop frequently and check that the drums or discs are not getting to hot meaning it could be more than just a rust problem.
Stop on a slight hill and see if the brakes have freed themselves by letting your vehicle roll freely.
