Caliper piston size?

[sidewinder69]

Is it common to have larger pistons in left rear caliper vs the right rear?

Not really. It is common on the front. It really wont make any difference unless you run a brake floater or something. Those rear wheel are tied together.

yep mastersbilt is correct, only time we ran that was when on the floater, we always ran a spool, so it might have an effect on some type of free wheeling differential, but ive never tried it....
