Help! Rear brake pistons don't move.....

[alwaysdutch]

I wanted to replace the rear brake pads today, but for some reason both rear calipers will not allow to push the piston back. The emergency brake is off, and I also tried to loosen the bleeder nipple. Fluid came out but no luck with the pistons.

I replaced the pads about two years ago and had no problem. Am I missing something that I need to do, or can it be that both calipers are shot?

Are you rotating the pistons CW while pushing in?

Yes, rotate clockwise. If it won't turn in, you'll have to either go rent a tool that'll turn and push at the same time (parts stores rent for free), or you can use a c-clamp to push and channel locks (but risk cutting the boot)

hopoefully you didn't let air into the brake lines when you opened the bleeder.
