N/a R34 Brakes And Rotors

[suprahb]

this is deffinately a noob question but i gotta ask this about the r34s, are there any differences between the n/a and gtt brakes? and how big the differences are?

another question the n/a r34 brake callipers, do they come with that nissan sign like they have them on the r33s?, my callipers dont say nissan, , i just wanna know if they are aftermarket or just standard? if they are aftermarket theres no real need in upgrading lol wishful thinking, anyhows, just shout out what you guys reckon thanks,

[scotty014]

i can help you a little bit. when i was looking for an r34 i saw a few at a dealership they both where N/A's one had the normal brakes while the other had the turbo brakes which is the one i bought and i love it. there is a big difference in size, the discs are alot bigger, im pretty sure i have posted up pics of them hear before as well. also they stop way better than my dads ford BA.

[scotty014]

i found the pic for you this is the pic of my car with the r34 turbo brakes. i know mine says nissan on them but i cant remember if the other ones said it or not.

[suprahb]

thanks for the replys guys, but i still need to find out what the n/a brakes on the r34 looks like, in sense do they have the nissan sign on them standard or is it just different for different models?

[suprahb]

here are some photos of my callipers, what do yous reckon? my rims are 18"s the callipers do look slightly smaller in the photo, this is the front calliper:

hey, so what do people reckon?

[SHANE666]

turbo brakes have nissan written on them.

non turbo brakes do not have nissan written on them.

- from my knowledge.

scotty from what i remember, youve had a turbo brake upgrade on your car before you bought it!

[Boss-zilla]

suprahb you have n/a brakes.

[DECIM8]

Turbo brakes are two pot calipers which means two pistons clamp down on the brake pads which are fitted either side of the vented disc brake. In the non turbo case, the brakes are single piston which means your brakes are basically half as good. Im not to sure if the pads are only one side as its a new car (most after 2000 come with double sided pads) but It may be single sided pad (doubt it tho)

In regards to the turbo brakes the disc is alot bigger obviously, even the rear disc on the gtt is bigger than that. bigger disc better braking/faster cooling. hope that helps

Futher infomation the GTV and the GTT comes with big brakes, gtr comes with brembo

Can I ask wtf did you get those impul stickers?

lol, came with the genuine impul front bar and impul rims its cool,

Turbo brakes are two pot calipers which means two pistons

This is correct for the rear but the front are 4 pot (2 per pad on the front on per pad on the rear.)

[Kranker]

Wouldnt say that 2 piston vs 4 piston, that 4 piston is "twice" as good.

Similar logic applys to brake pistons as it does to engine pistons. Having more doesnt necessarily make it better, but it may do.

If you had two sets of brakes, same size disks, one had 4 pistons clamping down on it each with 20cc capacity (4x20=80cc) (arbitrary values), and the other disk had 2 pistons each 40cc (2x40=80cc) the 4 piston brake wouldnt be 2x better, but it would be better nonetheless.

More pistons disperses the heat, load, etc more evenly/effectivley, and spread the braking force over a larger area of the disk, less chance of the disc warping.

In the case of turbo vs non turbo brakes, yes the turbo brakes are without a doubt better brakes, and are a good upgrade if you can get them at a good price.

When i bought my NA 34, the car came with DBA Rotors uninstalled. How much are these usually worth and are they a worth while upgrade ?

Depends on what kind of dba's they are.

If they are just a stock replacement, then the only benifit would be having new discs on instead of older and slightly to heavily worn (depending on how many km's the car has done)

If they are drilled or slotted rottars, then they give the pads more meat to bite in and the car would brake better.

If you car still has the standard GT brakes on them, I would keep an eye out for GTT brakes, find someone with a GTT who is getting bigger brakes and buy their old discs and callipers.

you might be lucky and already have the GTT dba discs and all you need is the caliper.

If the dba's are 908 (rear) 4908 (front) they are just standard GT replacements

the GTT turbos have the 4908 for the rear and 42304 for the fronts.

find out what you have first and then take it from there.

I was just wondering. I heard that the r33 gts-t and r34 gt disc brakes are the same size. Would it be possible to install r33 calipers onto my r34 disc brake without needing much mods done? How hard would it be? Seeing how it would be easier and cheaper to get r33 brakes then the r34 gtt brakes.

Just to set it all straight

R34 GT (na brakes) are exactly the same as the r33 gts brakes, they are a 2pot front/1 pot rear (neither have nissan printed on them)

The R33 gtst brakes are 4pot front and 2pot rear, but are totally different (rotors are larger aswell and calipers have nissan on them)

The R34 GT-T brakes are 4pot front and 2 pot rear, but are totally different to the gtst brakes (bigger again)

If you want to upgrade na R34 brakes, the "bolt on" upgrade is to get r33 gtst rotors and calipers. The R34 GT-T brakes dont bolt staight up, the main bolt hole needs to be drilled out to fit the bigger bolt from the GT-T setup

Will R32 GTR Brakes fit an R34 N/A ? Or is it only really the R33 that converts easily?

[R34GTFOUR]

^^ yep the whole lot will swap over (rotors and calipers) just as easy

the brake lines do vary though, so everything will bolt up but new lines may need to get made (same for the gtst)

Well I've got a R34 GTT and my mate's got a R34 GT non Turbo. Mine says nissan on the calipers with white writing and the non doen't have nissan written on them. Only the GTT Turbos have the Nissan written on them and the discs are larger on the Turbo from the non turbo.

[N-DAWG]

I'm looking to upgrade my brakes on my R34 Non Turbo as my fronts are 280 and rears are 265mm. Rather than start a new thread I thought it would be best to keep it in this one.

It seems clear that the R33 GTSt brakes are the bolt on way to go, however, a garage in Brisbane that specialises in Jap imports has told me that I'll also need the uprights for the front brakes.

Does this simply mean the upright arms? Or is it possible to just replace the rotors and calipers?

If someone can point me in the right direction that will be awesome.

Also if seems that all the rear brakes are the same and will bolt straight in nothing else needed? If someone can confirm that also?

I'm not so concerned about brake line compatiblity right now as I've been wanting to change them anyway so I'll get custom lines made.
