whats better? 300zx caliper?

[daredevildoug]

whats the better caliper off of the 300zx. iron or aluminum?
and who i running the iron calipers on there s13? thanks for the help

Alloy are better cause lighter.

[wootwoot]

The caliper also dissipates heat better than an Iron caliper, BUT the Iron calipers are wider so they might handle the exact load. Aluminum calipers are lighter, harder to find, and give better clearence for wheels

so goes the rumor that iron calipers were introduced to cope with warping/cracking issues of alum. calipers.
on the other hand, ive never seen a set of alum calipers warp on a 240...basically more brake than what most 240's have tire for imho.

It wasn't the caliper warping that was a problem, it was the rotor. The heat tolerances differ between the materials and some people claim to have had issues with the rotors warping under high heat because the calipers were not with the same range. I don't buy that theory at all though and have never had issues with mine.

just use thre z32 aluminum calipers because they're lighter than the iron ones and easier to find (91-up N/A and 90-92TT). They're all damn near the same size, and especially when coupled with the twin piston rears, its MORE than enough braking force a 240 could ever need.

[daredevildoug]

thanks for the heads up guys. i think i may go with the iron ones because of cost wise. more cheaper remanufactured. thanks for the help.

So let me see if I got this straight...

So aluminum calipers are found on 91-up N/A and 90-92TT

Iron calipers are found on 92-96TT?

Because hes worried about cost issue, but I priced some 92 calipers at Autozone I think it was, brand new, not remanufactured, and the guy said $100 for a pair. If thats $100 for two brand new aluminum TT calipers, then I'm going back down there today and buying all of 'em up!

[projectRDM]

No, that info is wrong.

ALL 90-92 calipers are aluminum, however NA models are 26mm, TT are 30mm. 93-96 are ALL iron, and all 30mm.

Rears are aluminum, 90-96.

[SpdElemts]

Why would Nissan change from an aluminum caliper to an iron one? Did Nissan redevelop the iron ones to be better?

[evilimport]

Only the NA 1990 calipers take the 26mm...the rest are 30mm.

The heat tolerances differ between the materials and some people claim to have had issues with the rotors warping under high heat because the calipers were not with the same range. I don't buy that theory at all though and have never had issues with mine.

just to compare notes:
i heard that it was the caliper. the rotor has very little to do with the metal of caliper. the warping of the rotor was a byproduct of caliper warping/flexing. the edge close to the mounting ears were said to go askew under heat, and when cool it would retract to within spec. but when hot brakes felt weak, mainly do to pots not hitting pad perpendicularly.
alumminum has a higher heat disipation which is a plus, but cast iron has a modulus almost 40% higher than allum. in most cases. this in a nutshell means alum flexes and cast will not. cast is more brittle, we all know this, but it is weaker than alluminum, thus iron calipers are built bigger and bulkier. so alluminum calipers are built lighter and have better heat dissipation. cast iron calipers have less flex, but need to be built bigger to componsate for less strength.
basically caliper heat sinking as it is called, affects rear brakes where ebrake is not an internal drum style(like stock 240 rear brakes). caliper heat sinking normally does not affect fixed caliper design, rather it sometimes affects full floating design, which leaves more drag on rotor because the slide bushings/pins might not move perfectly and thus caliper leave residual pressure on part of the rotor.
but like i said, it is a rumor, and with all rumors there are many versions. but anyways, for our cars alluminum is prob. the better way to go, as 30mm z32 brakes is more brake than most 240's have tire. thus the brakes will never be put to the limit where warping and flex is a problem. ligher weight and more clearance is defiantely a plus

[nlzmo400r]

go with the aluminum ones, they'r emuch lighter and worth the extra money, and you read my post wrong, here's the breakdown:

'90 N/A- 26MM ALUMINUM CALIPERS
'91-'96 N/A- 30MM ALUMINUM CALIPERS
'90-'92 TURB0- 30MM ALUMINUM CALIPERS
'93-'96 TURBO - 30MM IRON CALIPERS
ALL REARS ('90-'96) WERE ALUMINUM

i highly doubt theyre brand new? all autozones are the same and thats what the remanufactured ones go for.

anyways, theres write ups and specs all over the place. one on here is really helpful. i would highly recommend the 26mm alum. because you shave a combined unsprung weight of 1lb on each corner. plus they have plenty of braking power for the 240. unfortunately, i went with the "bigger is better crap" so i got the 30mm alum...basically, do what ever you want, theyre z brakes, any of them are better than what you have now...

[my240iguanas]

i think you should just get 91-92 30zx brakes , because whether it was TT or NA you still get Aluminum brakes

[infinitexsound]

u know there is a write up... get which ever u can get.. and go for the glory of getting it done.

wtf 100dollars a pair? i was looking for brand new alum calipers? nd if i buy from autozone do they give me actual oem ones or some gay aftermarket part that autozone makes? nd 100 dollars seem too low? do any of u guys know how much it is brand new. im willing to spend maybe 400 for brand new fronts. nd i want alumn rear ones too if there is any. or is it only the front. i cant find a price for brand new calipers, only remanufactured

theyre about 100 dollars a pair plus or minus 10 bux depending on if they give you the core charge back (your s14/13 brakes). they are actually oem and fully rebuilt. iirc, the only bad thing is that they dont come with much hardware (shims, pins, etc.). why get brand new when theres so many used sets out there, not to mention the autozone thing. why get brand new anything? theres not much point. basically rebuilt is new. all you should care about is it they function properly. and they do cuz autozone sandblasts everything and does all the seals. if the seals are still good, who cares if theyre used? ask anybody who has the z32 convo and ask if they bought brand new...BUY USED! :blah:

[XxJaPxOxNeEs23xX]

100 dollars is cheap tho. if i look on ebay and other places there like 300 dollars for the brakes. nd if the rebuilt one is cheaper ill get that too. look how much this costs

[infinitexsound]

used or rebuilt...dont get screwed if u buy used also.... make sure its complete...
[email protected]< dont trust this guy hes a very bad seller.. if u decide to buy some from the forsale section

not to bash on that dood, but thats a rip. thats way too much. he probably got the z convo and traded his s14 calipers for some z32s to sell. hey if your gonna scam them, might as well go an extra step right? i can admit that it crossed my mind :ugh: .

what ^ said. i didnt get jacked, but when i bought mine, i forgot to ask for the sensor that plugs into the z32 mc. just run a check list. if you want a price range: i got front and rear 30mm alum calipers, front and rear rotors, all the hardware (shims, pins, etc.), z32 1" mc, and a shit load of pads for $390. seals still good, all i need is the sensor and brake convo lines. hope that helps

[XxJaPxOxNeEs23xX]

the guy ssaid i cant use my 240sx brakes for the core, so its 150 for fully rebuilt. thats a pair with pads and all complete to go . nd the rear is the same.

:duh: :faint: YOU DONT TELL THEM THAT YOU HAVE A 240! TELL THEM YOU HAVE A Z! I THOUGHT THIS WAS ALREADY CLEAR ON THE OTHER THREADS! with the core charge, you save about 200 bux (50 a corner). now go back and DO IT RIGHT!!!

why do you think i used the word scam???
