Got a 99 GT and replacing the front calipers with a set that is powder coated. When I install the spring that goes inside the caliper at the center it cause the brakes to lock and not release. I have to push real hard to get the two mounting bolts in . When I take out it all goes together fine and works great, The powder coated ones came with the spring clip installed. I put the stock was back on and now they are doing the same thing....Ideas or does the spring clip on top matter ????
