How do you tell the regular A caliper from the wide A-caliper?
I know the wide ones take a larger rotor, but is there a "tell" on the wide A caliper in marking or measurement?

The wide a caliper has a wider spacer between the 2 halves.

Wait, don't all the A calipers have a spacer?

Wide M rear calipers have a wider spacer and a larger diameter piston than the regular M calipers.
