Noah,

I have also done rear pistons without opening the bleeder, 
but it makes the job a LOT easier, and if you are careful, 
you don't get air in the system, since you are just pushing 
out fluid.

But I will disagree with you on never pusing in to turn the 
piston.  There is no tool that I know of that will grab the 
notches in those pistons with NO pressure to hold it there.

Has to be SOMe pressure to keep the tool from popping out of 
the notches.  You may not be making a concience effort to 
push hard, but you are putting some pressure in.

But I think your point is that it isn't the pressure that 
retracts the piston, it is the threads...this make sense?d

Just a thought, continue with previous discussion please.
