Just noticed a few days ago at low speed and apply the brakes a get a chatter or knocking sound on right rear. I removed tire and noticed the outer brake pad has a lot of play, what can i do to eliminate the chatter sound. I have seen some plastic inserts you can buy are there any other solutions. Thanks

Their should not be much play in the pad you may have a stuck piston of the caliper, have someone step on the beaks to see if then the break pad has presure on it fron the piston to see if it is moving.

I just had a stuck piston on the right front.  The car pulled considerably hard to the left, at the same time I also noticed a high pitch squeel while driving (no brakes applied), I decided to completely re-build the entire front end brake system including bearings, calipers, rotors and semi metalic pads.  Works great now.
Another thing to check would be the parking brakes since it is the rear on yours, make sure they are not hanging up and the cable is free.

You should not have play.  That is not normal.  Check springs and parking brake and brake shoe.

Checked the pistons, they looked fine, took the pads out put the two back to back and noticed the outer one was slightly shorter in length. Switched the two pads back into the caliper and problem was solved.Smile
