Unbolt the MC from the booster and see if that frees them up. If it does, the brake booster rod is adjusted out too far and causing the brakes to drag. Turn it i n slightly

I doubt the brake pistons are not steel as im sure the engineers at ford would use nothing less on a part under this kind of stress. Polymers under such load suffer from creep and stress relaxation which = failure. Although it is highly likely that the piston has a polymer coating to prevent metal on metal binding....thats just my two cents from a polymer engineer
youve been misinformed. Ford tends to use phenolic caliper pistons on the higher performance applications. for the p71's the police interceptors use phenolic vs steel for civilian models.
Only because the Phenolic pistons transfer less heat to the fluid keeping it cooler and allowing less fade over repeated use. Good if you are driving a cop car hard which sees regular maintainence. In terms of durability though, he's right. Phenolic pistons tend to suffer more from sticking in the bore than their steel counterparts.
I'm pretty sure that the 99-04 GT's come with a phenolic piston. I'm going off memory from when i had a few sets before selling them all. One of the downsides is they are more prone to seizing...which is commonly seen. The other SN95 calipers use steel pistons.
Unsure if there is a steel version of the GT PBR out there, but that would be the way to go if you stick with the 10.8" brakes.
I had a feeling I picked the wrong ones. I got the Phenolic ones cuz I wanted to save a buck and thought they would transfer less heat. How long you figure I can get out of them before doing it again?
It was the caliper!Appreciate the response. I'll give it a shot!!
