<div dir='auto'><div>You are right Paul. Its probably just one of those fiddly things. Perhaps it could matter if the pads are worn down to their minimum and the rotor is worn, but I doubt it. Another reason might be changes in rotor or caliper design or manufacturer throughout the life of the model.

piston comes out as far as it needs to to press the pad against the disc.
After that they both press on the disc with equal and opposite force. As
long as the disc isn't rubbing on the caliper I can't see the problem.
It's not a Jaguar, Ferrari or Maserati where such things might be
desirable.</font></div>
