Help...15/16 BMC takes four lines?

[Mori]

Hey Everyone,

I have a manual transmission NON-ABS S14 with 26mm Z32 brakes up front and I'm getting ready to install the Z32 rear brakes as well. I bought what I believe is a a 15/16 Z32 MC based on some online info I read that stated it would install easily & be a mild improvement over the stock 7/8 MC.

Problem is that the 15/16 I received takes 2 front lines, 2 rear lines AND the fittings are on the opposite side from the 7/8, 1, and 17/16 MCs that I've seen. None of the 4 fittings are plugged and all have the flair fittings.

Has anybody else dealt with this & have any advice? The MC is stamped NABCO 15/16 and the box says 46010-30P10.

Thanks

Won't fit an S chassis AFAIK. Not all Nissan stuff swaps over. That kind of sounds like a FWD type MC.

Take pic. Still, what you described is not any z32 MC.

JDM stuff has lines on wrong side too...what car has 4channel ABS...maybe Q45 or J30? (jdm equiv whatever the F^ck)

PICS:







I got the idea for 15/16 MC from "The Definitive 300ZX Brake Swap!" page. The 460101-30P10 part number is suppossed to be for a 2/89-7/90 300ZX.

That looks like one for a right hand drive car, not a LHD one


You want them like this:

You can make that work. I use a RHD MC on my S13 (the tower is a little hamered for clerance):

Ya know looking at that now, that's an excellent way to keep the lines away from top mount manifolds etc etc. Nice post!

Where did you get the ss brake lines for that rhd mc?

Also, the mc I have has 2 fittings for rear brakes. I'm not sure if I could just cap one or not.

You have no idea what the split point is for that MC.


Just get the right MC for your car...

Thanks for the solid advice. I'm sending it back for a 1" Nabco BM50 MC (part # 46010-45P20).

Yeah. The Stock lines would have been VERY close to the manifold. I will fabricate a heatshield when my new engine is done.

The SS lines where made by a local Hydraulics company. Braided PTFE line witn some fittings. Nothing special.

Good idea. Brakes are an area where you really need them to be setup right all the time. Id you actually need to stop in a hurry you dot want to find our you've got messed up brake balance.

Type properly, Def. Autocomplete sucks.

I had a look in the 300zx FSM (Australia and Europe)
The splitpoint of the proportion valve is 3.432 kPa with a reducing ratio of 0.4.

That goes for both NON-ABS and ABS BMC's.

(Compared to 3.923x0.4 for S13/S14)
I still think you should see how the BMC you have fits against the turret.

Does anyone know if the proportion valves can be exchanged?
I want to put my S13 valve in my big 17/16" 300zx BMC.
