1994 Taurus GL 4 wheel disc, ABS. Only had it about 2 months. The pads look fairly new, however, I suspect rotor warpage, because when I get off Freeway or anything 55 and over I get a bad shake. Also, I doubt whoever put the pads on used the grease that you are supposed too. Anyway, I noticed when rotating tires the wheel was hotter than all the others. Also, I suspect the outer part is rubbing because the caliper on that side was lighter in color in that area. It is not a constant squeek, it increases with speed. Any ideas? The wife and I are currently out of work, so I hope to keep this on the cheap.
