Can someone confirm that the front and rear calipers take the same pistons?
I know the rings and seals are the same, therefore the O.D. of the pistons are identical; which leaves me wondering if the height(depth) of the pistons are the same front to rear?

 

They have different part numbers.
Front: 606683
Rear: 606696

 

Dang! Gonna check when I get home with some scrap calipers I have, but dang.

 

The front and rear are different. They share the same diameter, however the front pistons are about 1/4" longer. Drats.
