Well, after 16 years of ownership my car/semi garage queen has resolutely decided to join the ranks of the " classic car. " In short order the driver's door speaker went out and as soon as that was replaced the CCU shot craps ( thanks Brian K ). Since I was trying to get it back up to snuff i also replaced the failing trunk and hatch struts. Driving it today I noticed that the brake pedal is drifting toward the floor. There is no fluid leaking ( I change the fluid regularly ) so the master cylinder is bypassing. My question to everyone is should I get one manufactured by Nissen from Acura or is getting one manufactured by Centric or another aftermarket supplier just as good for less money and, yes, I did search but didn't find anything current on the subject.
Brake Master Cylinder

My master cylinder failed in the same way a few years ago. IMO OEM is the way to go, it's a bit pricey but for something like brakes I think it's worth it. Unlike the clutch master and slave cylinders where Centric rebrands Nissan parts the brake master cylinder they sell is some no name part.
*sigh*
Autocorrect strikes again.

Thanks for talking me off the ledge guys. It's hard to beleive that after all these decades of using only OEM parts in all my Hondas/Acuras I was thinking about cheaping out; on the NSX no less. I guess I forgot how annoying it is to do all the labor over again in a year because you bought a bogus part. Now that I have gotten my thinking straight I'll be buying a genuine Nisson part from Acura.

Neither Nissen nor Nissan nor Nisson, just Nissin. Sorry, I couldn't resist. :wink: 'Nissun' would be another candidate or if we take Turkish or Swedish into account: Nissän, Nissön and Nissün. 
Good decision, you should get the quality that lasts another 20 trouble-free years.

You say Nissin, I say ......
If you are in a hurry this won't be an option; but, Amayama has hard to beat prices for NSX parts.

Try a rebuild kit half as much?

OEM is NISSIN. There are independent suppliers of Nissin. Even RockAuto and Centric both carry the OEM as a knock off would be too expensive to put into production. If you cannot find a local supplier, I used S&L Brake Supply in La Crescenta in the past.

There was a thread a while back where someone bought the Centric and it was identical to the OEM Nissin, even down to the Nissin logo casting.
Wasn’t that the clutch master cylinder?

Whether it's OEM or aftermarket, please make sure checking the pushrod clearance.
I have noticed that some of the aftermarket ones have well over 1mm offset from where the OEM piston rod sits.
With OEM one, 99% of the time, you don't need adjusting as it's very rare for someone touching the pushrod adjuster.
However, I had to adjust on some of the NSX in the past so unless you know the full service history of your NSX, it's not 100% guaranteed even with the OEM master cyl.
The adjuster is behind the booster/pedal and thus, should be checked using the SST under vacuum.

I think you're right- it was the clutch master, not the brake.
Well I just installed a new OEM brake master cylinder and, while not as thrilling, it certainly is much nicer to drive when the brake pedal doesn't go to the floor. I bled the system using the same procedure as a brake flush without bench bleeding the cylinder with no problem. However, if anyone else needs to replace their cylinder do NOT throw out the old one until you have completed the job ( always good procedure with any repair) because the wires for the level float on the new cap are too short to connect to the harness so you will have to reuse the old one.
