has anybody done this?

the WJ rotor is about 5mm bigger OD and the WJ uses twin piston calipers, wondering if these could be swapped onto the JK dana 30/44 steering knuckles with the WJ caliper brackets to upgrade to the larger twin piston calipers

the WJ calipers can be had for fairly cheap compared to brake kits from companies that put the kits together

 

Persoanally, I've never heard of the swap but not to say it can't or hasn't been done. Have you seen it done? What caused your interest? Just curious. I know that with enough fabrication, anything can be done, it's just a matter of knowledge and money. Good luck with it.

 

no i havent seen it done but was kind of expecting to see twin piston calipers already on it from the factory when the WJ had twins on it with basically the same axle setup.

i think its time to go pull some brackets and calipers outta the junk yard, shouldnt really be and fab work needed, i'm thinkin the knuckles should be pretty close to the same

 

Majik on WOL (yes I know) is supposedly almost finished with a big break upgrade writeup that he dish bed himself that will be better than any option currently in the market (other than custom fabbed).
