most likely yes, jack up the front and spin the wheels. They should have a slight drag but turn in both directions. If they are hard to turn or don't move then the shoes are too tight and you will need to de-adjust them.
You'll need a brake spoon and go in through the access holes in the bottom of the backing plate, there should be rubber plugs in the holes (if the last tech that worked on them didn't throw them away). They should be in there to keep outside dirt and water out.
You can also use some compressed air and blow in through the back inbetween the hub and backing plate, that should get most of the brake dust out. Make sure you wear a respirator or have a mask on to keep from breathing the dust that comes out.
