my daughter just got a 1992 190E 2.3 and took it for a wheel/frame alignment (new right front 16" tire rubs, pushed forward compared to left & both tilt in slightly at the tops) but the shop refused to do anything saying "pads are too rusted and they won't heat them for fear it will fall apart". What is he refering to? And is there a solution? Is there a link anywhere to a diagram of this?
