Uprating the std s12 brakes Performance.
 

I am rebuilding my s12's std brake system and wheel bearings etc. I will be fitting new Pads all round and bleeding them.I also have grooved std disks to fit on at the same time

The s12 uses .3 brake fluid as standard. Has anyone changed to .4 and noticed any improvements or not.

what pads come highly reccomended from those of you who have tried a few different versions. Can we get Mintex pads for the s12 from somewhere? or are there other options? I have tried ferodo premier baggins pads and Halfords ones when i was desperate( Neither impressed me at all). I want to improve bite and reduce brake fade as much as possable.

I do not wish to change my hoses or change to the s14 brakes at this point before anyone suggests it ;)

Cheers in advance. :)

use dot 5 fluid as it has the highest boiling point and better water resistance than the lower number dot fluids, and will not cause any harm

In one day I changed to dot 5, grooved discs and budget Apec pads. Initially I thought the brakes were worse. But get them warm and they were really good.

Put them on the red car but never changed the fluid. I never really ran much power on that car for about a year so never excercised the brakes.

Dropped the engine in and then realised they were pretty shite but the discs were worn down and the grooves had nearly disappeared.

Fitted black diamond discs and standard Nissan pads and the brakes are shite. Haven't been arsed to change the pads for the pikey ones I used to use. But the pikey pads are twice as good as the Nissan ones. Might be the fluid but I can't imagine that causing a problem for normal day to day braking, that would only show up as a problem after a fair amount of abuse.

i would use dot5 aswell , i used it in my pulsar and was better than the dot 4 that came out, but i wanted a bit more bite (as pulsars are known to have really , really sh*te brakes) so i put in a set of black diamond predator pads , not great when they're cold , but once warmed up, peel your eyes off the windscreen, but what i was going to say was that all brake fluids up to dot4 are mineral based , have alot lower boiling tempreture , when it does boil not only is it inducing air into your braking system but moisture aswell , corroding your brake pipes from the inside out NOT GOOD , dot 5 however is synthetic based , it boils at a lot higher tempreture , i can't for the life of me remeber what it boils at though , i've got it on paper somewhere, but even a hard track day would struggle to make it boil, it's also down to brake set up too, ie the bigger the better , more energy scrubbed off quicker and better heat dissapation through larger disc's:)

they list the silvia 1.8 zx there quite goot, my brother has them on his vr6, hes got no complaints.

i think green stuff are more disc friendly, the red will wear i would think, but i dunno, just a guess :D

thanks people. .5 fluid and red ebc pads are my choice now.Thanks for the link umpkin. So they definalty do the red ones for the s12? The green ones dont seem to be suitable from there descriptions

i dont know, the link gave me a headache TBH if the numbers they give there are the red ones then yes :D else best to speak to you local stockists, im sure they will have a book etc.

I've heard from a number of different sources that EBC stuff is shit and that is from an old S12 owner and S13 and other people.

Mintex don't do S12 pads I've already checked through someone and they didn't come up. Porterfield are supposed to be pretty good.

Pretty sure you cant get reds for the s12 prob only greens. The reds are supposed to be better but some still say their shite.

:confused: now im confused again. I dont really want to listen to rumours though,i would like to get opinions from what people have tried themself

Shaun what do you use?

jon i've always used ferrodo baggins, but i don't really give the car much with the kids in, but the last time i slaughterd a scooby, i warped a disc braking fast a high speed:ghey so thats why i've rebuilt some z32 calipers and bought some braided hoses from earls, i've not fitted them as of yet, but i need to soon, as my pads are shot, the guy at zworld reccomends ebc, so i think if we listen to everything we here we would not have any pads in at all lol.;)

do all s12 rear brakes end up looking like this, cos ive had 3 now and they have all been fecked....

or have i just been unlucky? also ive got some new pads is it worth fitting them, or should i wait til i get some new rear disks as well.:)

Well I think the best pads available for the S12 is the Porterfield. This is from what I have heard Steve Carter say after comparing various pads. Red stuff isnt available for the S12 though. There is a new and old red stuff compound which is prob why people are saying they're shit on the basis of the old pads.

Don't know if EBC could be arsed to make a batch of them though.

Only half the pad is on the pads because someone has installed them wrong!

There is a location nipple on the rear of the pads that must slot into the piston. If not it will hit the disc on the piss just like yours.

The discs on the S12 are 22 front and prob only 12mm on the rear. One of the best way to get better braking is to get spanking new discs as only 2mm wear will reduce their ability.

do you recon the cheap ones off ebay are worth getting then?

£30 posted?

Might as well.

I would get new discs all round, some decent pads, do the fluid all in one hit.

i always make sure i give the discs a good thick coating of axel grease for winter use, it stops them rusting:eek: :D lol,(FOR FUCK SAKE DON'T TRY THIS AT HOME).

You say that but when I used to do a lot of riding i used to lightly spray the brakes surface with wd40 and it makes the brakes grab better:D

If I could get hold of Porterfield pads for £35 would anyone be interested?

These would be at least £80 normally

pagid do brake pads for the s12

i have a link on my home computer i will post it up when i get home thats where i got my grooved discs and pads from and the kyb shocks speedy delivery aswell

What are their specs about temperature?
What about them with our standard disc brakes?
Front? Rear?

;)

Just fronts.

They are ok with standard discs. They are a carbon kevlar compound

I'd go for a some of them 30psi, providing i can find some grooved s12 discs. Any ideas?

Try the motorsportworld website

http://www.motorsportworld.co.uk/

Various stuff on there which will give you a few choices

About the pads, do they ship to France?

You would have to buy them from me...

I have never heard of porterfield Martin but i am willing to give them a try,so if you can get some i will have a set for the front. BTW You can buy brake cleaner that you just spray on the discs. It works a treat.

3 sets are costing me £90 exc delivery.

So hows £35 plus delivery sound for my hassles?

Sounds good. I will send you paypal payment next friday when im paid. Il have a set 100%. Or you can have £ before that and i will scrounge it up.....I dont want to miss these

These are costing £93.50 for 3 sets.

Money ASAP please.

I'm having a set which leaves a set for Dan and Pukkasilvia? Any objections?

Tell me the full price shipped to France zip code 93310, please ;)

Objection Objection!!!!

I want some too :p

Ebc greenstuff
 

jon i have a line for you to remember from Wayne scholfield after he once tuned my motor with greendtuff on the front, " you need to change thos pads in ya car ken as they feel like they are made from dairymilk" so i recon that sums it up what da you think?????
I did'nt even get 5thousand miles from them either.!!!

30psi - sounds good to me still mate, my paypal is giving me hassles so pm me your address and ill send you a cheque asap.

put new disks & pads on the back of mine today, also some kyb's:)

Very tidy :cool: The inner arches and subframe look like they have been cleaned for a repaint?

Nice Trolley jack.

http://www.carparts-direct.co.uk/specialoffers.htm here is the link where i got my kyb shocks and drilled and grooved discs from and pads last year which i still have boxed ready to use when i get my silvia
speedy delivery i got mine in 24hrs from the moment i put the phone down and they are resonably priced too

Did they custom make the discs? I thought the s12 disc had an uncommon configuration that was hard to find.. ?
Which kyb's did you buy?
