If the vehicle has rear drum brakes it's possible that the brake shoes need lubrication at the backing plate. A squeak when releasing the brakes is caused when dry shoes rub against the backing plate pads. Removing the drum and inspect the brake shoe area where they contact the backing plate. Look for shinny spots or rusty areas. Lube with lubriplate or molly 77 if it's dry and recheck for the noise.
