  The square, "rubber"  piston seal itself.  The piston moves so little, 
when the brake is applied, that the seal geneally just stretches a 
little for the movement of the piston.  It then pulls the piston back 
when pressure is released.  
  Rear calipers are generally exceptionally fun since they have a 
racheting mechanism built into them for the parking brake.  That's 
where the 911 is kinda cool, standard disk with a little drum brake, 
just for the parking brake, in the center of it.
