Im toying with the idea of fitting big brakes front and rear and like the look of the D2 kits, but the rears cant be used with the oe handbrake and needs to converted to a hydraulic handbrake, which is a no-no for road use.

 

So my question is......does anyone know of a big rear brake kit with 4 pot calipers that still uses the oe handbrake set-up?.

 

Would like to do both ends rather than just the fronts as I think it may look a bit odd :)

K-Sport! I didn't know you had to change to hydraulic on the zed?

I have ksports all round. just bolt on and job done. but there 8pots at the front and 6pot rear.

 

No need to change anything.

I've got the fronts and am definitely sorting the rears in 2012 :) probably 4 pots

With the D2 rear kit you do, as there is no provision on the discs for the drum for the handbrake shoes

 

Car.mad.....are the k-sport kits a good fit etc?

I Didnt know that. D2 are basically the same as ksports so it would seem odd or and old school way to have a hydrolic one. it may be an old add, because many many cars have our set up so they may have sorted out the problem

 

Ksports are perfect in every possible way.

All the D2 listings I can find confirm the oe handbrake can no longer be used, and that goes for a lot of other applications as well, not just zeds :)

here are a few pics of the rear mate

Thats my mind made up, they look awesome.What size are the discs and your wheels?....i have 18" Rays off a 350z so I cant see clearance being a problem, what do you reckon? :)

cheers mate :)

 

The fronts are 356mm 8pots

The rears are 356mm 6pots with working handbrake lol!!

 

Im running 19" all round, so with 18" you might be better getting the 330mm just incase??

K sport should be able to tell you what the clearance needed is, then compare it to the inside diameter of your back wheels.

i will measure mine and let you know, all ksport will say is some 18" will fit but 19" will be best

cheers mate :)

Did you notice a huge difference in brake performance when you did this conversion and do they feel good? Humongous discs for the rears!

There amazing mate and worth every single penny. HUGE!!!! differance.

Ksports are a good bet mate, but be weary of internal rim clearances etc and the customer service is pretty shoddy

 

 

ref 8 pots front/6 pots rear, this is something that has been bugging me for a month or so now.

 

In a nutshell the shortie currently has 8 pot Ksports on 330mm discs at the front and OEM at the rear, however the other month when the front pads needed doing I had a garage try to fit the 12 pot Ksports on 380mm discs up front and 6 pot Ksports on 356mm discs at the rear, but the 12 pots were catching on the inside of my old Enkeis, so off they came.

 

I spoke to Kev at Apex Performance to see what he suggested and he recomended not to put the 6 pots on the rear with the 8 pots up front. I assume in my case that's because the disc size at the front would then be smaller than that at the rear?

 

I'm now in a ******* of a situation because I've got a set of RAYS fitted as a temporary measure, whilst I sort out the shipping of my pair of rear SSR's from Japan (Typically both the 12 pots and 6 pots fit inside the RAYS perfectly, I just don't particularly want these rims on the car permanantely).

 

I'm still in the same predicament as before as the 12 pots won't fit the Enkeis (the Enkeis's match the SSR's perfectly and are intended to go up front) :headvswal

 

I suppose what's important to note here mate, is that if you do go for a big brake conversion, check, check and double check that they will fit inside the rims that you want to stay on the car or it can get very expensive to rectify.

 

but Ksports are very good for the money bud

 

On a positive note, apparently my shortie' already has braided brake hoses fitted..... :thumbup:

No idea why i was told it was the best combo?? I have amazing brakeing force.

 

The front will always have the greater breaking force, even with 6pots on the rear. The only differance i can see is that you will get a more even feel?

 

If your 380's dont fit do you fancy a swap :lol:

It's because he'll be running 330 discs on the front and 356 rear, nothing to do with number of pistons

Nope :biggrin:

 

To be honest I followed what he was saying, the emphasis being that it wasn't the amount of pistons per caliper that was important (this led to a further conversation about AP vs Ksport which I wanted to avoid) but more so it's the contact area that is important (I assume by that he means disc size and pad size?) and that the best setup would be double brake effectiveness at the front than is at the rear (ie. 12 pots + 6 pots) with appropriate sized discs.

 

This didn't ring true at the time as I recall reading in JP or Banzai that the best brake set up would be 6 pots all round; and now they've told you 8 pots up front and 6 pots rear is best??

 

The conversation ended with me buying some EBC pads as a temporary fix for the 8 pots and basically them saying that if I was going to fit my 6 pots and 356mm discs rear then I would need to order another set of 8 pots with at least 356mm discs for the front but would also need to purchase a brake biase??

 

They offered to ship the 8 pots and 356mm discs to me the following morning, but I wanted a second opinion, so greatfully declined.

 

I might just have to bite the bullet and source another pair of SSR's for the front or similar Enkei's because I won't the 12 pots on the front just to see what they're like compared to the 8's

It's because he'll be running 330 discs on the front and 356 rear, nothing to do with number of pistons

 

That's exactly what I've put it down to

 

I always assumed (stupidly) that the discs and calipers were interchangeable but the brackets are obviously different, otherwise I could have put the 330mm at the rear with the 6 pots and kept the 12 pots up front but with the 356mm discs....obviously I learnt that that couldn't be done because the front and rear discs centres (?) are very different also

I have a stoptech big brake kit for the track. I haven't bothered as yet with the rear but it's a possible addition if I really need it. Brake balance is essential as I know from experience where my rears were locking up under hard braking (track) and it was partly down to master cylinder I believe. Anyway, even with the stoptech we had to go for bigger pistons than standard to provide more stopping to the front. Have a look at this link for info
