Actually bill the rotor is what gets shimmed. The runout is measured with the rotor secured to the spinning hub. The caliper really plays a very small role since the pads kind of 'float' over the spinning rotor. The factory rotors are riveted as you know, so runout issues would be isolated to bearings. When replacement rotors are installed typically the rivets and removed but never replaced. In some cases people tap the holes and use counter sunk tapered head bolts to secure the rotor after runout has been minimized. Without the runout being checked, the rotor is free to wobble and every time the wheel and rotor are removed it changes. Hence the rivets or bolts. |
