Back in the summer I innocently had one of these "brake job places" do a free inspection on my 560sl. I asked them to hand torque the wheels after determining that I still had a few thou miles left on my pads and rotors. I guess that "piss'ed them off and they way over-torqued them. Shortly after, my brakes started to shudder and I ended up replacing the fronts.

Did you have your wheels off at all lately?
