Sometimes mine require a bit of reverse turning before trying to compress. I remember turning and turning for what seemed forever. I then reversed the direction briefly then continued. They seemed to compress much quicker at this point. Give it a try! One of my rears does require a little more work than the other, but they both work fine in the end.Yeah it is the right rear piston I have tried to depress and spin it at the same time and still no gain. I think It might be the hose but I am not sure I will try this tomorrow.
Thanks for the responses.
