S14 front brake set up
 

I have finally finished putting the whole thing together so thought it would be good to put a how to :cool:

The s14 callipers will work with the standard s12 brake set up, You will just need to get some braided hoses made up with s12 end put on for the main brake line side and s14 end put on to go onto the calliper. You will need these to do the full set up aswell. I got goodridge to make mine up, you can ring them direct and they were not much more expensive than getting a set of standard s12 goodridge ones. You could also try Hose Solutions, i have had a few things made by him and he's really gd and cheepest i have found so far.

Having just the s14 callipers in did make a lot of difference and was a gd easy fix but there is quite a lot of work to do the full set up.


Complete set up

When i got my s14 callipers i bought a standard nissan recon kit for them, its a bit fiddly to do but worth it in the long run.

To start you will need to strip the front hubs apart and remove the bearings. You will need to change the wheel bearing now this is all apart, dont buy the wheel bearings from nissan as they will cost a stupid amount of money. What i did was took the bearings down to a local industrail stockest that did bearing and they checked the codes and even had them in stock, the 2 bigger ones were about £10 each and the 2 smaller ones were about £7.

Due to the old s12 disc bolting at the back where as the s14 disc slips over the hub and wheel studs, the s12 hub will not fit into the disc. This will need to be machined down. I was lucky and have a friend who is an engineer with all the tools but a local company should be able to do it for you.

Now you will need to get your disc redrilled from 5 x 114.3 to 4 x 114.3, i was lucky again as my mate had made a dolly whiched used one of the existing holes and showed where to drill the others. You could get a local machining company to do these. Or alternatively you could buy a set of already drilled discs off someone on the sxoc.co.uk, there is always ones for sale.

Due to the s12 discs bolting to the back the wheel studs are only short on the front. I found that the rear wheel studs are just long enough to use, im not sure what they are like for lenght with most alloys as i am using hubsentric bolt on wheel spacers.

With the hub reasembled its starting to take shape

I made up the whole strut and refitted them back to the car

When originally looking at doing the full set up i thought i was going to have to make up new calliper brackets as i was fitting a bigger disc but on a test fit i realised these was just enough room for the disk to rotate without fouling the calliper

The only problem was i needed spacers making up to offset the calliper so it sat in the middle of the disc. After a couple of trial and errors i found that the spacers should be 11.5mm long. I got mine made out of a piece of steel bar.

With the callipers fitted, i put the pads in and tightened up the braided brake lines. I think the set up looks the bollocks now :D

Thats such a good How-To.

Im sure it will be a really big help to a few people. I will probably end up doing it to my next s12

spacers
 

These spacers would do the trick

yea those wheel spacer are the same as mine just mine are H&R:)

What is the diameter of the s14 discs compared to the s12 ones?

from what i can remember the s12 discs are 274mm diameter x 22mm thick and the s14 discs are 280mm diameter x 30mm thick

is the first pics s12 disc's :confused: , i can't get my head around the pics mate, the top pic has'nt got a center in like the lower discs, or am i getting mixed up, have you got a pic of an s12 and a s14 disc side by side so i can get my head round it, i'am not with it today lol.:D

yea the first pic is an s12 disc. no sorry never took a pic of the discs side by side.... should have really

so the machining is on the s12 hub, the outer bit, so the center of the s14 disc can slide over it ?

yea thats right :D

i wonder if they are the same as the z32 discs, i know the calipers are the same exept the z32's are ally and a lot lighter, i had a z32 disc for an example, but the bloody scrap man took it with a lot of scrap off the back yard:rolleyes: , have you thought of anything to uprate the rear ? i read somewhere the other day about usind z31 rear arms, hubs, discs etc, as they use a vented disc on the rear.

yea now that i have done the rear i have found out that the s14 use the same type of s12 hand brake mechanism, but as for the discs and callipers i have never looked into them.

There wont be any need at all to uprate the rear brakes to something from another model. :cool:

great how too m8.

as for the rears, these days its not bout uprating the rears, more of changing them to something servicable i.e being able to get the parts easy for it.

BTW, the S14 calipers will work with 315mm brembo discs as supplied by Dans Brakes from SXOC :) Might have been worthwhile doing that (although bearing in mind that they are bloody heavy, bells would be lighters).

Yeah could be easier to save the hub machining by using the larger M3 discs.

I ended up overcooking some rear brakes, the vented Z31 discs may be a reasonable type of upgrade option if someone was going to change the discs.

Its also not necessary to change the front wheel bearings when its been upart.

Im surprised if you found the std rear brakes to be insufficient

What happened?


A healthy setup with decent pads and at most a few grooves is all that should be needed

On really heavy use they overheated to the extent that they were smoking and faded. At first I assumed the rear calipers were seized on, but they turned out to be free when I jacked the car up.

The vents must count for a lot but don't know if you'd feel the difference unless you are going really heavy on them.

Unfortunately the brakes are great on the S12 but just don't stand up to continued heavy abuse.

Was this still with std front calipers?

Yeah but note that the rear were more knackered than the front. Reason I got out the car to look was the smell and whiffs of smoke more than anything. But kids, if you do cook your brakes don't remain stationery as it can warp the discs as the disc cools unevenly.

I haven't driven my Datsun in anger enough to see how the rear drums fair up after some abuse. Not used the brakes to any decent capacity on that if I'm honest. Only tested to see if the balance has gone a wrongun with the Z32 calipers.

The S12 has a 1" master cylinder, which is actually bigger than an S13 ones, so its not essential to upgrade to the Z32 ones which is a plus.

Dans big brake kit would be another good alternative, you would prop have to be running a set of bigger alloys than just the standard 15's. Just found out that my mate has got a set for sale now :rolleyes: Things like that always come around after you have done something else. :)

Whats the smallest wheel that fits on the brakes, i bet it's r16.

And about the rear brakes, not that they would be insuficinet or anything, its just that it is very hard to find parts for them (like lets say rotors, i ende up using z31 non turbo solid ones, identical excpet for the 5 hole mounting setup). On the other hand, i doubt that the z31 ones (the good, vented ones) wouldnt be any better.

Its 15" but it actually depends on their spoke design. Standard S13 wheels will require 5mm spacers so the spokes clear the caliper

i borrowed a bmw disc mart and the disc still will not fit over the s12 hub, it needs a couple of mm off of the s12 hub, do i use one of the holes on the bmw discs as well ?

That's weird when used on an s13 hub the BMW disc is too large a centre bore. You could use one of the BMW holes but it will need to be ovaled a bit to match the pcd. The other 3 will need drilling

i've got r32 calipers now and found out they sit further away than the s14 calipers, so in theory i could use gtr 295mm discs with a 11.5 mm spacer like doski has used, only for some reason r32 discs are extortionate price at £150 each:eek:, i'd like to use bigger discs but i could live with 295mm instead of 274mm std ones, i'am not going to be trackin the car only straight lining, so they should be adequate until next year, then i will probably do what you have done mart.cheers for the help.:)

i though s14 are 5 holes and not 4 ?

yes, but you get them re drilled to 4 stud mate.:)

i used skyline r32 discs in the end.

Current I got R33 GTST dics and calipers here. I think this will fit too?!

Can't you use the standard front discs with the s14 calipers?!

Also will they fit under standard s12 wheels?

I think they will buy will just need the wheel spaces to stop the calliper hitting the wheel I think
