Are the rear calipers different that the front? I thought I read somewhere (maybe here) that when you go to push the piston back in (when installing new pads) that it's threaded and you have to actually bleed it down some and screw it in. Is this true?

Thanks

 

yes, you have to turn the rear pistons clockwise while pushing them in

they have special tools at any auto parts store to help but you can do it with some needle nose pliers if you're careful, just dont damage the boot around the piston and dont scratch the outside of the piston
