Breaks making noise when I apply them at stop
 

I have a honda civic 1993...My breaks make noise when I press them at a
stop sign or any any intersection, when the car is completely stopped.
I don't get a noise when I press them during driving. I had my pads,
rotor, and wheel cylinder replaced only within last month or so. In
fact, got the wheel cylinders changed only like 2-3 days ago. The noise
is like grrrrr... something.. It seems that it is coming from behind of
the car, somewhere close to the closet.

Any ideas?
