Why? I am about to go for a track day at Hallett Raceway May 11th. I normally just Autocross my car occasionally.
The organizer recommended I change to fresh fluid, and I thought to go with higher-temp fluid while I was at it.
So, I bought some Motul DOT 5.1 fluid for the higher boiling point, and it arrives Wednesday.
And I have a simple hand style vacuum pump.
Here is the question: Do I drain the entire system, and refill? Or do I drain the reservoir, refill with new, and pull in new fluid at each wheel (and the clutch)?
Is there a risk of issues letting the system get air into it? DOT 5.1 does not absorb water (and it isn't silicone based either).
I hope someone with a B-spec or similar experience can give me some advice.
