Time to pressure bleed the entire system.


The traditional theory of bleeding from the furthest point from the brake master cyl won’t apply for some of the modern cars.


In fact, you can’t even bleed the air on some of the models without activating their ABS modulator.


For most of the latest ABS on NSX, S2000, etc, you will bleed the system from the front side.


You can still use the old theory but it may take extra time and you will waste more fluid.

So, pretty much done with the ABS Upgrade.....


 Will leave the car on the lift over night for leak check, quick test driving session and should be done for the ABS upgrade.


 Needs to work on the Left driveshaft and the dirty A/C blower fan…

    Kaz, I just completed this upgrade myself. I used some of your documentation. Kinda interesting, right to left, left to right comparisons. You can plug those old ABS soleniod connectors together. There are two female and two male of each kind. (cleans it up a bit.)
    Thanks for this. It helped answer some questions before I proceeded.

    Hi, warrenw.

    Congratulations on completing one of the most important projects for our early model NSX.

    From the brake balance point of view, best to combine it with the later spec callipers but even with the original ones, still big improvement compared to the original ABS.

    Installation is much easier on the LHD NSX than the RHD one.
    You have more space around the Rear brake/Clutch pipe 6 way joints.
    Makes big difference on the time being spent for the spaghetti brake pipes installation.

    I guess you managed to get all the parts especially the ABS modulator before the sudden huge hike in the price.


    Hope you are enjoying your new setup.

    You are correct, the rear brake/clutch junction block is the most difficult to get at. I used four wrenchs to get the job done. two different flare nut wrenches that were about 15 deg different from each other, a flare nut socket with a long extension and a very small 10mm fuel line wrench. (this was the necessary tool because it was not only small, but one end was 30 deg offset and the other 90 deg offset. I could not imagine this being a tighter place to work on a RHD! I got in on a last order or last search buy SoS and I paid about $200.00 over the orginal price for the entire kit, so not too bad. Chris at SoS will put you on a waiting list as he searches all the Honda parts wearhouses in Japan. That is how I got mine. Good value I figure. Even though I could exercise the old ABS in 30 minutes, I was getting tired of doing it twice a year. Not to mention the sound of that ABS pump.
    Thanks again!
