lynchfourtwenty Posted January 10, 2009 Author Report Share Posted January 10, 2009 so is this question just to dumb to answer? Quote Link to comment
Edz280zx Posted January 10, 2009 Report Share Posted January 10, 2009 I don't know...I know the 280zx is an uprage on the 240's when you swap to disc brakes on the rear. Sorry, maybe someone with more knowledge will speak up? Quote Link to comment
lynchfourtwenty Posted January 10, 2009 Author Report Share Posted January 10, 2009 now that i think of it i would need it to be for front disk rear drum ? do any zx's come with that? im wonderin what it would take to make a d21 mc fit.. or something bigger then the one i have because i dont like how far i need to push the pedal down to stop... i mean im dont jamming down hard or nothin an i dont have to pump it but still.. if u drove my truck u would know what i mean Quote Link to comment
BEEBANI Posted January 10, 2009 Report Share Posted January 10, 2009 I have the 720 m/c (15/16") with booster in mine, wasn't hard to do, just extended the 620 bracket Quote Link to comment
lynchfourtwenty Posted January 10, 2009 Author Report Share Posted January 10, 2009 pics?? and how does it feel? do you use the 2 piston or single piston calipers? Quote Link to comment
BEEBANI Posted January 10, 2009 Report Share Posted January 10, 2009 singles all the way around and it's solid, there's only one m/c that's bigger (300zx) Pics are in my project thread Quote Link to comment
datzenmike Posted January 10, 2009 Report Share Posted January 10, 2009 up to '78 620 3/4" master '78 and '79 13/16" '80-'83.5 720 7/8" '83.5-'86.5 720 15/16" '86.5-'88 d-21 15/16" Quote Link to comment
lynchfourtwenty Posted January 10, 2009 Author Report Share Posted January 10, 2009 cool cool looks like i found my answers thanks guys Quote Link to comment
yello620 Posted January 10, 2009 Report Share Posted January 10, 2009 Or run a 280z 7/8" master, they had rear drum. I am running a 15/16" 280zx master cylinder with my front disc/rear drum and it works great. Pedal feel is excellent. Quote Link to comment
lynchfourtwenty Posted January 10, 2009 Author Report Share Posted January 10, 2009 mods needed for that swap jason? Quote Link to comment
lynchfourtwenty Posted January 12, 2009 Author Report Share Posted January 12, 2009 so yello620 is there mods needed for that zx mc? i forget.. also what about the 720/d21 mc? do i have to use the booster also? is it a better idea? what mods are needed to make it fit? Quote Link to comment
yello620 Posted January 13, 2009 Report Share Posted January 13, 2009 mods needed for that swap jason? Absolutely none, bolted it right to my 76 620 booster. Been on the truck this way for almost three years now. Quote Link to comment
lynchfourtwenty Posted January 13, 2009 Author Report Share Posted January 13, 2009 hmmm what year / model zx? was it a all wheel disc? or rear drum?? i think i might pick one of those mc's up.. the turbo zx m/c i tried to see if it would fit wouldnt even bolt up :( Quote Link to comment
yello620 Posted January 13, 2009 Report Share Posted January 13, 2009 The 280z is 7/8" and the early ZX is 15/16" that bolts up and the late ZX bolt pattern changed. Mine was made for a 4 disc car. Quote Link to comment
lynchfourtwenty Posted January 13, 2009 Author Report Share Posted January 13, 2009 so i should ask for a 79? 280zx 15/16 M/C ?? or maybe a 80? so even tho its a 4 wheel disc m/c your drums work fine? i figured it would be too much for em.. Quote Link to comment

IIRC it was 79/80 that fit and 80-82 that didnt fit. C'mon it was three years ago, i cant remember now:D Quote Link to comment
Edz280zx Posted January 13, 2009 Report Share Posted January 13, 2009 82/83 is different style than my 81. So 79-81 should be the one you're looking for. You'll probably have to get the resevoirs from a junk yard as the M/C's I've bought didn't come with them..had to swap over from my old one. Quote Link to comment

lynchfourtwenty Posted January 13, 2009 Author Report Share Posted January 13, 2009 in this pic they look to be about the same... am i correct? Quote Link to comment
Edz280zx Posted January 13, 2009 Report Share Posted January 13, 2009 Same as the 620? Quote Link to comment
lynchfourtwenty Posted January 13, 2009 Author Report Share Posted January 13, 2009 as far as the resivors swapping yes they look the same size dont they? in my opinion they do.. the m/c i also notice does have the same mounting style :) maybe this summer i will get some rear disc shit goin on if i can find some rear brackets :) Quote Link to comment
Edz280zx Posted January 13, 2009 Report Share Posted January 13, 2009 If you say so..lol, I really have no idea as I haven't paid attention to the one on my 620....it just sits and rusts..LOL Quote Link to comment
