first you should inspect the rear brakes and hardware to make sure the springs and hardware are still in good condition and not broken, then inspect the shoes and check to make sure they are installed correctly, primary shoe in the front secondary in the rear. check for leaks around the wheel cylinders and axle seals, once the rear brakes are in good working condition if the problem still exists you should try replacing the rear brake hose first to see if it fixes the problem.

Check to see if shoes are diging into back plate as this happens on lots on trucks. some grease on back plate where matal on metal happens.
