R32-300zx Brake upgrade: B13 /B14 / P11

.:PROZAC:.. · Postby **.:PROZAC:..** » February 22nd, 2009, 10:48 pm

Hey guys, although most of you may know this already ;some of us have asked or are interested in doing this for our own cars. I jsut put it together for myself but maybe it would benefit someone else.
Taken from friends and experience. Feel free to add.

The are 3 types of nissan 4 piston calipers.
30mm iron
30mm aluminium
26mm aluminium
each with their specific thickness rotor.

Stock SE-R brakes:

Piston area = Pi (r^2)
Brake surface = 3.14 (22.5^2) x 2 = 3180.86
Brake surface = 3180.86

On Z32 brakes:

Piston area = Pi (r^2)
Brake surface = 3.14 (20.25^2) x 4 = 5153
Brake surface = 5153

So you have around 62% more braking power on the front than a stock SE-R, you also have more mechanical force with the bigger diameter rotors, as well as better resistance to get the heat up the brakes, since you got more material on the bigger and thicker rotor and a bigger caliper helping with the heat distribution.

B13 / B14 Z32 (300zx) Brake upgrade

And this is the part list:

Z32 calipers: (duh!)
I highly recommend to get the ones from the 1990 N/A 300zx, as they fit better in our little cars, and they wonâ€™t need a massively thick rotor.

U13 Altima (or G20) brake rotors:
They have the same diameter as the Z32 rotor (280mm), its a little bit thinner though (22mm vs the 26mm of the N/A Z)
(for those who want 4x114.3 all around use g20 rear hubs it bolts into your rear b13 spindle and this is a fact not speculation. Now you can have a P11 like me yaaaa! I think it should also work on the B14 as they share the same spindle-spline pattern.)

U13 Altima master cylinder:
It will be helpful, considering you have in one single wheel, the same amount of pistons you had in the whole car before lol

And this is the heart of the project, nothing makes sense, and nothing will fit on your car, unless you have this:

B15 Sentra Steering knuckle and hubs:
Yes, this means your front wheels will be now 114x4. But the Z32 caliper and Altima rotors will fit, right in. No adapter plates, no custom job. But most of the aftermaket wheels have 100x4 and 114x4, as my enkeis.

Optional parts:
This depends on the wheels you are using, due to spoke design of my wheels, I had to run spacers now.

Unfortunately, is not that easy, while bolting everything in, we found that due to the B15 knuckle, the rotor needs to be reduced in diameter 4 milimeters, or otherwise it will hit the caliper. So you have to take the rotors to a machine shop before bolting everything in.

I think is a good bang for the buck conversion, considering the ridiculous price out there for 4 piston brake kits. I will post some pics of the final results right now.

P11 Brake Upgrade

S14 calipers (30mm iron or aluminum, 26mm is also an option but then you need thinner discs).

S14 discs (280 x 30 mm) and drill them to 4 x 114,3 and turn them to 276 mm, or atleast that's what I did. Or buy discs with this specs OEM.

S14 pads (remove the wear indicator on the pad nearest to the wheel 'cause it can hit the wheelhub)

Sunny N14 banjobolt (2x) (the N14 banjobolt is shorter from the factory. In fact, the N14 bolt is the exact length you need if you should cut the P11 bolt (minus 5mm) so go to the Nissan dealer and buy these! It's plug n play!

P11 brakehoses (or Goodridge)

4 new bolts + washers to mount the calipers (always a good thing to have fresh mounting hardware)

Brake fluid (I did DOT5.1)

It's all plug 'n play now!. Car on jackstands, remove wheel, remove 2 nuts on the rear of the caliper, remove bajobolt, let fluid leak into a pan or something, remove caliper+disc, place new disc, place pads into calipers, put caliper back on, fit new bajobolt and make sure there's no air in the system.

Oops, I forgot 1 thing. You need to cut away the splash guard and grind/sand down a little bit (1mm perhaps) on the inside of the caliper cause there is a chance that the discs will scrape a tiny bit.

If you want to keep your 4X100 bolt pattern with these brakes on a B13/14, just use Y11 AD wagon spindles (wingroad is 4X114), and re-drill rotors to match.

Me and a guy argue this point.. I wish he could read this and STFU :lol:

1990 N/A 300zx i came across this but the calipers were single piston ?

what are u refering to as the sterring knuckle ?
is the G20 the same as the p11 or p12 or both ?

DF1_2nR · Postby **DF1_2nR** » February 26th, 2009, 3:00 pm

G20 = P11

Boneyard · Postby **Boneyard** » February 26th, 2009, 3:21 pm

also when they say kuckle do they mean the spindle ?

Boneyard · Postby **Boneyard** » February 26th, 2009, 3:39 pm

i was doing some research and just wanted to make sure maximaJ 30 SE (93-94)

is the USDM name for Cefero and if yes then cefero rear calipers can bolt directly

on to b13 hub ?

PROZAC Are you sure the inner diameter of the rear wheel bearing on the G20/P11 and the B13/14 are the same? I was told that the P11 bearing is larger in diameter, and has to be sleeved in order to fit.

I've been thinkin of doin this conversion on my B14 for a while, just wanted confirmation from someone who done it before.

wagonrunner · Postby **wagonrunner** » February 26th, 2009, 7:12 pm

G20 and B14 seem to carry different bearings.
the shape and part numbers are different according to the FAST

P11E has the same part number, and shape as the B14 though.

yakuza · Postby **yakuza** » February 26th, 2009, 7:19 pm

wagonrunner, do you have pics of exploded views of each application?

.:PROZAC:.. · Postby **.:PROZAC:..** » February 26th, 2009, 7:50 pm

Is there a difference with the USDM and jdm bearings?
I know it will work on the USDM B13 can't vouch for the b14 though.

yakuza,
P10 = P11E = B14.

G20 seems to be a different version altogether.

It shouldn't be, because I used JDM hubs,spindles,rotors,calipers,sway,LCA,UCA and it worked with no issue.

Ok, only thing I thinkin now, is if the USDM B14 wheel bearing is larger than the JDM B14 one.

click the link, and you tell me.
<a href="http://forums.trinituner.com/forums/viewtopic.php?t=231114">WTB: Y10 rear wheel bearing</a>

this is what i'm looking for, to replace what is in my current banjo.
this banjo was bought foreign used and installed.
all replacements i'm seeing the flange is notably thinner, and bearing width is thinner as well.

what size do you guys normally see?

Which 4piston caliper and rotor will work 4 my B15. Also will the P11 rear disc brakes work on the B15

Skyline calipers will bolt directly, you have to redrill the rotors to 4X114, and the P11 rear disc will work also.

any fairly easy fixes for placing rear discs on a y11 ad that came with drums?

Yup..

The Y10 wingroad that came with rear disc brakes will bolt right up... no need to hot up your head. There is just one little mod that needs to be done which is to put a larger eye and bushing for the rod on the Y10 Banjo ( this is the rod that runs from the Banjo to the Body of the car close to the gas tank area . )

Another rear disc conversion that can be done is using the Aviner rear disc set up from the Diesel Aviner. ( I am not 100% of this but I have been told they are identical to the Y11 Wingroad rear setup )

P11 can work also ( A friend of mind did the conversion on a certain Boosted Y11 ) but you will have to fabricate brackets to relocate the caliper location to work on the Y11 Banjo. ( you are not using the Primera Banjo you are scraping the P11 rear disc setup and putting it on the Y11 Banjo ) This the P11 setup is still running strong 3 years now with out any issues..

I am looking for the Y10 Wingroad rear disc setup... anyone knows where I can get it ?

Anil_Sooknanan · Postby **Anil_Sooknanan** » March 19th, 2009, 9:09 pm

yes the diesel Aviner works bolt for bolt. the conversion your talking bout using the P11 rear on the Y11 i'm going to try it this weekend. i had a y10 sold it for $1200

Carrot · Postby **Carrot** » April 30th, 2009, 11:11 pm

been looking for the y10 banjo with the disc brakes for my y11, but that ting come like gold in de bamboo....no one has it. They all have the B14 rear disc setup or the P11... what kind of fabrication will I have to do for the P11 brakes to work on my Y11? Thinking about trying this way if no luck with the Y10 banjo. If anyone knows who has the Y10 banjo with the disc brakes, please let me know....
