Apparently the Freestar rear disc brakes do not have an automatic caliper adjustment mechanism. Meaning as the pads wear play develops between the piston and the pads. You need to use the parking brake on occasion, which adjusts the calipers. It sounds silly to me, but it worked on my Freestar. I was at about 50% on my pads and they started really rattle by merely going over road cracks and manhole covers. After reading a blog on this problem I tried the parking brake as suggested.

Poor design in my opinion, but using the parking brake a couple times a month works for me, saving hundreds or more at the shop.... - Visitor
