How can rear caliper piston rotate back out on 2003?
I just finished putting new disc pads into the rear calipers of my 2003. Posts here warned to not just try to compress the piston to make room for the new pads but that the piston must be screwed back to make room, so that is what I did.
Also, there are two little posts that the piston face must align with before the pad will fit. In any case, can someone tell me how the brake fluid pushes the piston back out to engage the rotor if it has to turn at the same time? This looks like a mechanical screw system so I don't know how it is caused to rotate so it will come out to engage and also as the new pad wears down. Thank you, Willydo Tucson |

The turning of the piston is for the parking brake. It only needs to turn to go in, not out.

Dan, Gearhead....thanks for the info
Guys, thanks for the information.. I was just a bit concerned how the system worked.
