I believe that's a 3/8 allen wrench, but it's a really simple matter to get under the vehicle and try different wrenches on until you find the correct one. Many calipers are held on with a 3/8 allen bolt, but some are 10mm and some even 1/2 regular bolt.
That is a 3/8 Allen.
== == Yes. Flat to flat is the correct measurement to take to determine which size of driver (Allen wrench, hex key, etc.) you have.
