Hello,
This an assumption, but for rotor concentricity, how about creating a sketch that contains a 3 point circle on the [EDIT: center of the ends of the] caliper pins/bolts.
Create an extruded surface using this circle.
Then do a contric mate with the rotor and the surface.
After this, hide (not suppress) the surface.
The other mate can be a distance instead of a coincident mate.
A coincident mate will wear your pads out prematurely.
Cheers,
Kevin C.
Hello again,
Another (more thought out) approach:
You can adjust the angle for the angled plane if 45° doesn't work for you. Everything should follow along w/o any kabooms.
I hope this helps,

P.S.: This post has a whiff of homework on it.
If so, be sure to give proper attribution for any assistance you recieve, but also demonstrate all of the new SW tidbits you learned from this assistance.
It's a good excercise on using reference geometry for mating.
I assume you are referring to the center of the disc to the pad? If yes then for the ones I use, I set up a sketch in the pad model for the size disc I am using and mate to those. If I do not do that then I try to model the pad where I can use distance mates from the planes. Hope this helps.
