Carpet, Interior Panel, Health Check, etc 01

Rate this Entry






Started to work on another NSX from last week.
The service menu is to carry out the Health Check, replace FL wheel speed sensor, replace all cabin carpets to 02+ NSX-R spec and replace grey interior panels to the later spec black ones.




I already knew this NSX was triggering the ABS and TCS warning lights for the FL wheel speed sensor issue so no point in going out for the test driving session without being able to check the ABS/TCS.
So, decided to replace the wheel speed sensor first.
The existing sensor was open circuit so probably the MPU wire windings were cut due to heat cycle of epoxy sensor body over years.




I already knew the front brake pad was fairly worn but didn’t realise it was already down to 1 – 2mm left before hitting the warning metal tab so decided to replace it together with the front disc as well.

Normally, EBC is good at in keeping some stock and while there was no problem getting the front brake pads, the disc was big headache.
I don’t want ordering brake products through these unknown source on ebay as the disc inside the package from well known brands could be different.
As always, EBC was very helpful and tried helping me out but the earliest they could get hold of the suitable disc was late/May so not ideal.


Thank you to Anthony at Burn! Motorsport.
Although it was out of stock, they were very helpful in sourcing the Dixcel PD brake disc for early models.
Bit more pricey than the EBC but not much and as I always used Dixcel while I was in Japan, I know the quality so hope I can get the delivery very soon.
I know some of the Dixcel discs used to be manufactured in UK so not much point in going back and forth between UK and Japan but at this good price, doesn't matter.

Just need to figure out the most efficient way of moving the car off the lift while waiting for the delivery......




As expected, the sensor head got lots of oxidation over the years and stuck in the mounting hole so had to remove the hub bearing first.




By the way, with the tyre on the hub, couldn’t feel it but when I rotated the bearing with my hand, I could feel tiny change in friction so probably one or two bearings are bit worn.
Some grease is seeping out a little so once you can start feeling the friction even with the tyre mounted, just replace it.




Despite the presence of the o-ring at the sensor body, huge amount of the oxidation.... It's everywhere..... No surprise as it was the same when I replaced the FR side long time ago.




Cleaned and polished the area slightly and then applied tiny amount of silicone grease just on the metal surface to prevent future oxidation.








New sensor installed.
