There was a thread on this same part a while back...

I think it has something to do with a safety feature of the brakes... I THINK

I can' remember very well so don't quote me on that. Searching for "nitrogen canister" should yield some results.

Wow, really expensive. I was wondering if anybody has changed this part.

Note that this is only for cars with traction control. My '91 does not have it, even though it has ABS.

I posted this on the UK site a while ago as I have an imported JDM LS400 ( Celsior) and it has this to operate the traction control ( well apply the brakes to the rear wheels).

As you can imagine it has a lot of pressure in there to operate the brake hydraulics so please don't mess with it unless you know what you are doing.

Providing you don't have the trac light flashing ( i.e in use all the time) the canister should last the life of the car.

In snow I turn my trac off as it makes little difference to grip and doesn't use up the gas needlessly.

Apparently there are specialists that can refill the cylinder if needed but the trac light should come on to indicate a fault should it run empty.
