How Joohn I have an A3 of ´00 and the same thing happened to me. If you have tried to push and then threading and the embolony has not moved proof to push and thread at the same time, I did so and without problems. By the way to do this is a useful that will make you very facilitated work. Greetings and you will tell me
Hi John, the piston goes to thread, but be careful with the overalls to see if he is going to crack. Pilla a purple and you are going around and he only gets into a bit will cost a little but then he more easily enters.
Hi Joohn, as the companions say the caliper piston you have to thread, there is a useful for that job but if you do not have it roscalo with a peak parrot clamp while a little luck and greetings.
