i am going to fully flush the fluid.
i got 5 bottles of motul 600. each at 500ml. that ought to be MORE than enough right?

Jewels

Way more then you need...2 bottles should be plenty.

6gt3 capacity is 0.63l. You should be able to do a lot of flushing w/2.5l.

0.67 ltr on the 7.

! liter should do it. Why not Castrol SRF? Also, as others have observed, the rears do get hotter than the fronts.

I use RBF600. It has a higher dry boiling point than SRF. The benefit of SRF is on long term use given the high wet boiling point, this is not a benefit for me as I bleed my brakes for each track event.

SRF comes only in 1L bottle. Once you open the bottle, if you don't use the entire content, the dry boiling point starts falling during storage. RBF comes in 500ml bottles, and it's way cheaper.

thanx for the info.
i plan to try SRF next, but i have ah... let see... maybe 24 bottles of motul in the garage that i need to use up... dont ask.

exactly 2 worked for me

1 l should be enought, right? I just got hold of some SRF, they only had 1l however but Porsche told me that it was enough.

Moot, you're overdoing it. Just go track the bloody thing.

ps. A 1 liter bottle cuts it (about $80 at Winecountry ...) but you can't flush it yourself, you need to take it to Christian to cycle the ABS into service mode to flush it, otherwise, you're not getting 100% fresh stuff through to the back of the pistons and the whole value of the SRF is wet boiling-point, otherwise you should use Motul which is almost the same dry point and far cheaper.


Here's the BPs again (and as far as I know, the dry BP of Motul "Red" RBF600 is not higher than the CRF point.)


Brake Fluid boiling points dry/wet and price per litre (approx quart) :

590 / 518 ___ Castrol SRF $75
536 / 396 ___ ATE Super Blue $10
572 / 284 ___ AP DOT 5.1 $9
572 / 302 ___ AP 551 $12
590 / 410 ___ AP 600 $18
593 / 420 ___ Motul RBF 600 $30

mooty

yes, abs has been cycled.

Sorry to bring-up an old thread, but I am getting ready to DE my 996 (OK not a GT3), but where are you guys getting the Motul RBF600 from ?

Thanks in advance...Steven

You might visit Alex at Sharkwerks.

(Rennlist sponsor and knows 996's.)

You should be going through a pretty long checklist for your first DE with a 996, especially suspension and alignment.

There's numerous posts comparing each available type and brand of brake fluid. You probably don't need to pay for Motul, but it is very good. ATE has never let me down in several 911's driven pretty hard at the track.

Enjoy the DE -- being prepared is the key to enjoying the day.

TheSpeedDemon

Thanks and I will check with Alex since he's a mate of mine, just did not think of him at first

Yep I am getting prepared and will be attending my first DE at Thunderhill in April with the PCA-GGR. Tech inspection first then some other things.

Thanks again

My Mechanic is High on RBF600 it has a real high boiling point and its cost is reasonable. I think its like $20.00 a btl. Does anyone have any down side to this its cheaper than some of the others that have a lower boiling point. I think RBF is 600 plus? anyone have any thoughts?
