Audi Break problems!!!!

Hello I have a big problem whit my Audi S6 (in fact it's a small
problem)
Today when I was driving to a store the car started to make a horrible
sound from the back right wheel. like a stone grinding against the break

disc. I had this problem on a Audi before but then the problem was
solved
by driving back and forth and breaking hard. This time it doesn't seem
to help (and it sound a lot more). So my question is how do I dismantle
the break calipers to remove the stone or even remove the shield behind
the break disc? (that's probably there for preventing things like this
to happen)
