Brakes
 

It seems that my brakes are done for, but when i started looking for new rotors, i could only find this, and they also say in there that they can get you EBC redstuff for the front and greenstuff for the rear for anout 90 pounds (thou i dont believ that thay have it for s12). Does anybody know if these rotors are any good?
Maybe any other options for some cheaper rotors?

Black diamond do disks for s12, can get them from http://www.motorsportworld.co.uk/ :)

I always thought that s12's front rotors diameter is 250mm but on those sites it says 270(something)

Hiya,
I`ve just had a look in the s12 bible;) .
The rotor outer diameter for European cars (ca18 and fj20) is 274 mm and the rotor outer diameter for Non-european cars (ca20) is 250 mm.
Hope this helps.:D
Regards,
Ian.

Yeah like theres a lot of cheap rotors in USA, but sadly they dont fit the euro spec cars.
Well black diamond's even more expensive, for now that ebay item is the cheapest i could find. I dont want to invest much in these brakes, because some time in the future im planning to go with a z32tt brakes swap (not that i need them or can afford them now :D ). So anything cheap?

a set of standard disks and gd pads will be just as gd:)

I could bet that oem standart discs (not that anybody else makes them anymore :D ) would be as expensive as some diamond black discs (atleas in lithuania). Anyways the z32 swap is the way to go, much better breaks for real serious driving, but i realy dont have funds for that right now.

P.S. Oh and a z32 brake master cilinder would make it almost perfect.

Not that it really matters, and I'm not trying to offend, but it's 'brakes' when referring to the car part, and 'breaks' when referring to something that's broken :)

What fitment are S12 discs (PCD?). Perhaps Dan at DB Power can do some Brembo M3 Disks for the S12 cheaper, as I remember he ran a group buy for the S14 crowd with redrilled disks (It is what I had on my S14a).

I'm running some of those ebay brake discs and they are fine, 1000000 times better than my old disc's, but they were knackered.

You can order just the fronts etc if you have a word with the chap selling them.

They were also cheaper than a stock pair of discs even with a discount from my local motor factors.

Any idea on the brand though? Cheaper no-name brands are likely to warp with any serious use.

Matthew

Oh thats i right, i totaly forgot that, i guess my english sucks a little :D .
I have heard of the m3 disk convos for s13, but if I remember it right, that was the front only, my big problem is the back, thou id like to change all of the rotors. Also dont you have to move the caliper further away when using the m3 rotors?

Also what about the EBC pads. A few people have been telling me that theyr latest products have some quality issues.

I didn't notice your from Lithuania lol. Would have tried being more polite about it :)

Not sure about rear disks but something similar could be done on the cheap I would think.

The bracket you're talking about is just a flat metal section to increase to make allowance for the different offset of the new disk (m3) and the increased diameter. Something you or a metal worker could make very easily as long as you have the correct dimensions :)

Matthew

Well mine are fine for fast road work on a stock S12 (using red stuff pads). Thats all I can say as thats all I know.

If you wanting to use them for competition I would personally approach a manufacturer direct and ask what competition discounts you get for running sponsorship on your car.

How much were the red stuff you got for yours mate ???

£40 for the red stuff pads with the discs, might be cheaper elsewhere but much less hassle.

very unlikely to work, s12 discs sit inboard of the hub. I think z31 discs are 296mm (have to check though) if they are r33 gts calipers would be ideal to go with them. now stop giving me ideas

What pads do you have?

Danny... GET CHECKING!!! (oh and p.s. what size wheel minimum would you need to fit 296mm into? [obviously we are not sure about caliper size as of yet]).

Don't know about the pads. Anyone else know?

knew i'd seen 296mm discs somewhere

You can just have the discs drilled to attach to the hub from the rear. Someone with a datsun with s12 legs tried it with Z32 discs and the caliper was correctly spaced as well.

i have nearly finished a full s14 brake set up on s12 hubs, need long wheel studs , s14 disk redrilled to 4 stud and the calliper will need spacing, i am just getting some spacers made up think they need to be about 11.5mm:)

let us know how you go on, i have the s14 calipers, but with grooved s12 discs, i'd be interested in getting some bigger fronts on there and what about the rears, is there anything we can do to improve those ?

Be worth trying to get the disc redrilled so it can be bolted to the rear of the hub before trying to make spacers

should work the same with the M3 kit then. nice

Yeah but it will be to the PCD of the inner hub bolts which arent the same as the PCD of the wheels me thinks. But if the offset this way isn't an issue then for this method its a damn handy upgrade

Is it hard to swap s13 brakes? I could get the whole seat quite cheap.

s13 discs won't go on without the above difficulties and the calipers are no better

yea i ran s14 calipers with s12 disk before which was gd but just thought i would go for the bigger disks which i thought i would need to mount the s14 callipers onto brackets but when i went for a test fit i found that the s14 disks just missed the inside of the s14 calipers so happy days. :)

Another thing i had to do is i got a mate to machine the hub down a bit, from being more square i got it taken down so it was more like the s13 ones, rounder. The s14 disk now sits over :)

With the rears i didn't look into any brake swap... didnt want mess with the hand brake mechanism. I rebuilt the caliper and put some new disks and pads in. I now belive the s14 runs the same type of rear brake set up as the s12... o well think there should be enough stopping power now lol

I guess then i have no choice but to go z32 up front. Maybe somebody can post up a pic how to fit the z32 (or s14) disk with the caliper on the s12 hub.
But what to do with the back? Are there atleast any decently priced rotors for the back (not 150 pound diamnod black's)?

Rear upgrade would be to use Z31 rear discs, and quite possibly the calipers if they designed for a wider disc.

Z31 rears are about twice as thick because they are vented.

i will do a full how to once i have the finished spacers from my mate and have them fitted :)

Dosent the z31 have a 5 lug hub? Thou vented discs sound nice...

Yeah, redrill them. Nothing is bolt on for the S12 so you have to adapt things to fit.

Ultimately you could run Z31 rear hubs, wack on some cheapo S13 coilovers and S14 hubs, fit a Z32 or S14 set of brakes and also convert to 5 stud at the same time.

Yeah i know, but all at once is abit costy for me at the moment (thats why i wanted some cheap stock rotors for the moment, too bad they dont exist).
So if im going z32 front, i guess then the better option would be m3 rotors, instead of z32/s14. But then it struck me while going home: i most probably wont fit a r15 wheele on this setup, and thats bad because i would need new rims and them damn expensive r16 winter tiers :mad:. Damn what to do....

What about z32 rear hubs/brakes?

doubtful, look at z31 stuff though, not sure how good they are but might be worthwhile

With regard to the M3 Rotors, I would say that they are pretty darn heavy. You might get better peformance buy getting custom bells and rotors? (Although at a much greater expense :( )

Matthew

Scored myself some decently priced rotors :) These
And ill be getting some z31 rear ones, they seem to be the same as s12 (290mm x 10mm, dont know other specs) just 5 hole.

This just proves yet again that you just have to give ebay some time, and youll find what you want.

Now the next question is brake pades. I could only find some greenstuff and balck diamond predator. I would rather not buy ebc so this leaves with black diamond, anybody know anything about these pads? Or maybe its possible to get some other pads, like ferodo...
