Apply pressure while turning?
I have run into this problem years ago, and do not remember the solution. Had to do pads on Mamma's '03 MkIV TDI, and I can NOT get the pistons to wind back in. If I go backwards, they will IMMEDIATELY wind out, but when I switch the reatchet and try to retract, they just sit there where I stopped and spin around.
Kind of a panic as I have to leave for the bush tomorrow and she needs her car.
OK, if anyone is interested: The deal is that you need to push back a wee bit of fluid before whatever is inside contacts whatever holds the thread still for clockwise loading, THEN it winds in very easily. Now I remember looking at the tool long ago and not liking the idea of continually putting pressure on the threads.
Auto Zone or other parts stores may have the tool for rental. I work in an undercar shop and have used mine i dont know how many times with no problem. Just slowly put the pressure on it. Like someone else said turn a little add pressure, and keep doing that. As long as they turn your good. Just watch the boots that they dont twist on the piistons and rip
