front brake pads on 2003 Chrysler Sebring

what wrench is needed for front brake pad replacement?

Asked by for the 2003 Chrysler Sebring
After removing the wheel the caliper has a dampening spring clip on the out board side of the caliper, on the in board side there are two plugs that need to be popped out to gain access to the caliper slide pins. From the illustration it looks like an allen key is needed to remove the pin but there is no mention as to the size in the manual.
