Brakes problem
2005 Chrysler Town and Country 6 cyl Front Wheel Drive Automatic 45000 miles

calipers are held in with what looks to be an allen bit > or torq bit? do you have a digram or any ideas ?

Since you need to get the tool anyways, get a 3/4 drive bit. Stop at the parts store and tell them what you need. IF needbe they can pull a caliper off the shelf to match it up. I like to use a breaker bar with the socket for better leverage and keeping it square to bolt. I'm not sure of the size.

IF you email these folks they may be able to supply it as well.
