I'm interested in knowing who some of the larger manufacturers of calipers and micrometers are. I know that Mitutoyo, Starrett, Brown & Sharpe, and Mahr are all big, but who are some others?

I am a new Harley owner. I took off my back wheel to try and fix a noise and do
a little deep
cleaning. I failed to take a picture of the thing before I took it off and now i
can not
remember the placing of the spacers. Here is how I took it off:

-I removed the nut and pin on the pulley side.
-I then , using a socket set, pulled out the axel on the rotor side (with rotor
side nut in place.
-I pushed the wheel forward and took the belt off and removed the caliper and
the metal
pice that attaches the caliper to the frame ( I'll call it the caliper arm).
- removed the wheel.

Now I have three problems:
-I can not remember which side the small or large spacer goes on.
-On the rotor side, does the space go between the frame and the caliper arm or
between the
wheel and the caliper arm.
-Which order to put the caliper, caliper arm, and the wheel on so I do not
scratch up the
wheel.

Can anyone help me out with the three issues?
