Rear Caliper Piston Twist Left or Twist Right?
Alright so im trying to fix this brake issue and i decided to replace my pads since they need to be replaced anyway. Using the brake wrietup http://www.audiworld.com/tech/wheel139.shtml and the same tool used in the writeup purchased at harbor freight i went to retract my rear driver side caliper. Well i find out the piston is too far out for the tool to fit.... What i CAN do is use the tool to rotate the caliper (but not rotate and press at the same time). Im wondering what way the caliper is supposed to rotate: clockwise or counterclockwise? I tried both ways-- clockwise= less resistance counter= more. Also when i was doing this a little brake fluid leaked out of the seal for a brief second and then stopped and it hasnt done this again.
My questions are- which way should i rotate the piston? does it need both pressure and rotation to retract or can i just rotate until there is enough space to fit the tool? What did the quick leak of brake fluid mean, and does the seal or caliper need to be replaced? If you must also press the piston while twisting, would it be possible for me to open the bleeder valve to relieve pressure so its easier to press while im rotating with the tool?
Any help with any of those would be appreciated.. Ive had it with this brake job, especially now that it got colder here.

Alright i actually just came up with an idea where i twisted, the c clamped, and twisted some more and that did the trick so sorry i posted that big paragraph. I am still wondering about the momentary leaking seal though..
the leak shouldn't be a problem at all. I just did my brakes and lines last weekend, and at one point the piston in my drivers side front end POPPED OUT of the caliper and a whole bunch of fluid smothered the ground!!
You are supposed to remove some fluid from the system -from the reservoir- before you push the pistons back in, so that it should not be filled to the max. I suggest about an inch lower than the max line on the reservoir.
Anyhow, I just put the piston back and made sure the rubber was properly seated in the groove around it, and all is well. Brakes are still great!!
