now that i think of it. doesnt one set spin and one push in....or am i thinking of anohter car.
The caliper bleeder screw should be opened to drain the caliper when pushing the piston in. It's not a good idea to push old contaminated fluid back into the master cylinder.

well it's a good idea to change the fluid every now and then any ways.....i'm gonna have to change my pads soon and i'm planing on doing the fluid at the same time soooo.....no worries there
