GM uses a 3/8" Allen wrench. 10mm may also work.

Thank you very much,

Any suggestions for changing you pads and rotors in 3-5 inches of over night snow??? hhahaahah crap....

Update, completed pads and rotors in about an 2 hours. Had to add some torque to the GM allen wrench by hooking in a crescent wrench. Thanks again for the size. 17 degees, light snow, 10 mph winds. Good Times. Best purchase, my new mechanix gloves.
