I'm trying to put new rotors and new Hawk Blues on my 325 and I can not get them on. So I measured the new rotors at .865 and the new pads at a combined 1.370 for a total of 2.235. Even with the old rotor at .856 the total clearance needed is 2.226.

I measured the distance between the caliper and piston with a clamp squeezing in the piston and it was 2.192(max).

I didn't notice any need to install the piston in a certain position to get it fully retracted, so I am assuming that 2.192 is the maximum possible clearance.

Did I miss something or do something wrong in assembling the caliper?
Or do the Hawk Blues need to be shaved to use them?
