NSX Health Check Service

[Kaz-kzukNA1]

After bench bleeding the master cyl by tilting the cyl at specific angle, it is installed on the car. Pressure bleed the system, left it overnight for the leak check then test driving session followed by another pressure bleed and leak check.


ABS flushing.

While driving this NSX at low speed with window opened, I noticed that the ABS pump was operating almost like every 10sec so I knew the solenoids are leaking or the accumulator bladder is not holding the right pressure.


Using ABS SST to release the high pressure fluid from the accumulator.

Flushed the system twice before moving onto the solenoids flush.

All four solenoids were not sticky and operated fine which is a good news.

Flushed the system again twice and waiting for the test driving session.

However, looking at the amount of high pressure fluid returned to the SST, as predicted, looks like we may have accumulator issue. As discussed, considering the usage of this NSX and condition of other ABS parts, it would be more cost effective to invest in the ABS upgrade than trying to replace the parts on this original system.

This will leave us with replacing the Engine Oil & Filter, Main relay and refurbishing Bose speaker AMPs, test driving session and another bleeding with leak check so hope to return this NSX very soon.
