Welcome to AF!
I have no idea, but I can suggest this, don't drive it anymore until they fix it.
If you make it worse or the problem breaks something else, don't expect them to take responsibility for it....
...gotta love those factory trained AND CERTIFIED technicians! No one can screw up a simple break job until they get their certification... if it is an easy job that you can do yourself, then do it your self. You would have been better off paying a couple kids to do it, because if they don't know how to do something, then they would open up a book and follow the SIMPLE instructions...don't have that done at a dealer, EVER!!!
If you can, Id say buy a Haynes manual, and if you can, never take your car to the dealer ever again...
Im sorry, but Im a do it yourself kind-a-guy, mainly because I find it hard to trust others to do it right the first time...but in this case, they broke it, so let them fix it.
