You have to TWIST them back in.

See post #3 ... it's all there.

I'll will have to try this next time ... the pistons were very difficult to turn without opening the bleeder screw.

Just talking about changing pads. You can refill whatever fluid was lost through the bleeder valve, but you dont need to changeout all your fluid.

I wouldn't take my brakes quite so much "for granted". Just because you can't see through the brake system fluid boundary does not mean that moisture can't slowly seep through or around it into the fluid.

Worth reading.

Especially since the typical Mustang owner is likely to drive that car a little harder and be more demanding of his brakes than your garden-variety Corolla driver.

Copper concentration is the current buzz-word as an indicator of fluid age (and boiling point).
