One thing you might try is to using heat resistant silicone. Take the capiler off removing brake pad apply the silicone around the highest edge of the capiler where it touches the brake pad. Apply a thin coat over the back of the brake pad. Let dry and reassemble. If chatter is what you are getting this may alleviate the problem it also should give the added tension.

If the caliper piston is sticking, replace the caliper. If the caliper yoke is sticking in its guides, clean the guides with a wire brush. Some caliper yokes make use of shims and bushings in the guides to reduce friction, these may need to be installed or replaced. Check with your dodge dealer regarding those shims.
