> Does this front rotor to caliper clearance look right?, Seems tight

I dont remember the clearance being so close when I took it all apart.

Is this normal?

I can only fit about a .001 feeler between the rotor and the caliper on the outer side.

This is a 71 with what I thought we determined was a late front strut.
When I tried the early rotors, you could not even get close to putting the caliper on.
Now with the "late" rotor, the caliper just barely clears.

I thought maybe the wheel bearing wasnt seated all the way, but I re/over-torqued the nut to see if it needed to pull in any more, but that didnt help.

Ok, when I first posted, I had .002 clearance on the outer side of the pass rotor and ~.090 inner.
I installed the drivers side and had .030 outer & ~70 inner
So I thought it was the bearing not being seated on the pass rotor.
Took it off reseated bearing races, put back on - same measurement ( maybe a .004 now)

So I took off the drivers side, checked the race seating, and put it on the pass side.
Pretty much the same as before (both rotors act the same on pass side too tight on outer clearance)

So I swapped calipers and I get-
Drivers side caliper to rotor clearance:
Outer .020 Inner .075
Pass side:
Outer .017 Inner .086

So "Around 20 thousandths" seems like it could be the expected value for caliper to rotor clearance on the outer side.

The rotors are both brand new and measure .430 each. (~11mm)
And the late pads fit.
One caliper just seems to have a slightly larger opening than the other.

So I guess I'll just have to say that it could be part variation (stackup) that makes one combo of caliper+strut be too tight.
I didnt bother to swap it all back again just to prove it's repeatable....

Anyone else ever measure the caliper to rotor clearance?
