datoman-1000 theres no doubt what you specialize in

ok, its off a datsun ute which had front discs tho?
will it suit disc front end? i think im goin s13 front brakes:P

I would say yes, but you will have to remove the residual line pressure valve (if it's still there), which is located above where the flare nut goes in (only the one for the front)

Probably too small for S13 setup
Might need to step up the the 13/16 Sunny one..... S13 ran 13/16 master too
