I just had the rear brake shoes replaced on my 05' Fofo and also had the drums resurfaced. Picked up the car yesterday and this morning I noticed a loud hummin noise when applying the brakes until I make a complete stop. The noise only comes from the Right Rear drum. When the car is moving at any given speed, I do not hear this noise. Anybody have an idea on this issue? Thanks in advance for your comments. [werd]

is it a constant sound? or a intermittent sound that speeds up as you go faster?
If its constant i'd say the shoes are dragging & weren't installed properly. If it is a humming it could be that also, or it could be the wheel bearing if the mechanic over-tightened the bolts on the drum.
I'd suspect the shoes weren't installed properly. Take it back to the mechanic for sure!

Jack up the rear of the car and see if you can easily move both wheels, if you can't then the brakes are hanging up or the wheel bearing bolt is to tight. Either way take it back to the mechanic and have him fix it.

you're not to re-surface focus drums,, they have a special coating

When I am driving, I don't hear the noise. When I am slowing down applying the brakes to a complete stop, then it is when I heard the noise. The noise is light, but when it almost comes to a stop it pitches louder until the car stop.

^^^^^A special coating on the drums.....on the contact surface? After a few miles of use, whatever coating that was on there from the factory, would be worn off completely.
The problem with turning small drums like these is that they are really difficult to setup in a standard brake lathe. I suspect the finish on the newly turned drum is defective, and causing the noise. There's a single big nut holding the drum onto the spindle.....I doubt the problem is with the torque on the nut.
If you would pull the drum off, you'd probably find a finish you could feel with a finger-nail. Bad.....

Thanks everyone for the help. Indeed, the surface on the drum was rough, looked like if the brake lathe started making vibrations hurting the finish on the drum. I had to get it resurfaced once more, but the drum is shot. This morning I found a good auto parts store that sells them at 29.94 plus each including the bearing. The noise was reduced, still I'm going the extra step and replace both drums. Also, I will take the brake shoes back to the parts store for warranty. They were the ones that resurfaced the drums the first time(Don't wanna roast them, but they have an Irish name).
