A fella brought in his Avanti the other day for some brake work. The disc brakes were not working right and it appeared to me something was amiss. No shims on one side and some unequally distributed on the other. We all know the book says to shim until centered. I ask the gentleman who had worked on his brakes last. He indicated some shop in his town and the name of the owner. I called these brake specialists and possed a simple question. Why is it important to follow the service manual and shim the brake caliper until it is centered correctly? Fella told me that I didn't know what I was talking about, and shiming wasn't required as the caliper would right itself as pressure equalized in the system. I'm no brake dummy, but when the professionals can't explain it, or get it right, what's an average guy to do?
Now I ask you, why is it important to follow the service manual and correctly shim the caliper? What bad things could result if you don't? I can tell you one thing that I found. Premature pad ware on the inside resulting in grooving of the rotor, which resulted in the right front pull the customer was experiencing when braking. Quick ratio steering is mighty touchy!
