'06 Civic EX Rear Caliper
 

I'm new here and just had a couple of questions. I just bought a 2006 Civic EX coupe the other day and am replacing the brakes. I got to the passenger rear, and it seems the caliper is frozen. is there a way to fix this or should I just replace it? I know its a screw type piston, but it won't budge. also looking at the pads on the other 3 wheels I probably could have gotten some more miles out of them, but on this one they are about down to nothing.

If I replace the caliper, anything special I should know? Or is it as eay as clamping the line, removing the line, e-brake cable, etc and then the reverse and bleed the caliper at the end?

thanks for the help!
