Chrysler Repair: T/C Van 4 wheel disc caliper guide bolt tool, wheel disc brakes, haynes repair manual

Question
I have a 2001 Town and Country van with 4 wheel disc brakes. According to the Haynes Repair Manual that makes the brake parts the Continental Teves brand. I need to know what type / size tool or bit I need to remove the Caliper Guide Bolt. It looks like some kind of hex or allen key socket but OReilly and AutoZone folks have no clue what it is. Hope you can help. Thanks...  

Answer
Those guys did not sell you a thing!!!!!Get a brake tool
socket set,it comes with"torex#35 to#50 and allen metric

a13mm.socket,so,lets go with the guess.or drive there
and turn the wheel all the way to the left and you can see
the caliper pin/bolts..have them take a look.
