I've been noticing a squeak when I've been driving and it'd get worse when I apply the brakes. Thought maybe the pads were down to the indicator. So I jacked it up and pulled the wheel off and checked the indicator. It's still got a little ways to go. Then I try to rotate the rotor by hand and it wouldn't budge. Ok, so maybe the slide pins need to be cleaned up and relubed. So I removed the bottom caliper bolt and pried and pulled and tugged and finally got the caliper to lift up. That was then I noticed the dust boot around the caliper piston was torn. I also had a hell of a time trying to get it off the top caliper pin. Yeah, the caliper pins are bone dry and sticky. So, I may either take the calipers in to get rebuilt or just buy new calipers. Oh, and that squeak was one of the little metal anti-rattle pieces. It was touching the rotor and applying the brakes would move it closer to the rotor. So, looks like I got another project lined up.
Here's the pictures so far. Might as will replace the pads too since they're cheap anyway.
Edit: I just tried to push the piston back in with one of those "squeeze" clamps and it wouldn't budge. I know when I did my brakes on my Cobalt, I was able to push the piston in by hand. So, looks like it's seized.
