I want to change over to ATE Super Blue, but I'm not sure how much fluid I need. So, my question is this, how much fluid, in liters, do I need?

Hey Chris,

Are you doing this yourself? I switched over to SuperBlue back in November. I went over to Ultimate Autoworks and the did it for around $50 (I think).

$50?

That's not bad at all. I was planning to do this myself, but at $50, I just might go for that.

I think the brake system will take 1 liter of fluid... so you should have an extra 1 liter, just in case.

Yeah, I just checked and it looks like it takes 1.5 quarts which is a little over 1 liter. So I need to purchase 2 liters, but I'll have about 3 quarters of a liter left over.

Anyone know where I can find Axxis Ultimate pads online?

Chris,

By the way, I am installing my Scroth 4 point belts on Saturday morning over at Ultimate. So, after that if you want to check them out let me know.

I am thinking about doing the ASRA event at Firebird on Feb 14th.

Adam,

I would definitely like to meet up and check them out. Although, I got a little anxious and got a set already....but I'd like to meet you anyway.

I am planning to do the NASA event out at PIR on the 21st-22nd of February.

I went the conservative route and purchased 4 bottles of super blue. I now have 2 unopened containers in my garage.
I would recommend 2 bottles, but an extra third is nice to have around the house for any future line bleads.

JaWeb.....whenever its time for a fluid change again.....grab the SRF....yes its more expensive, but well worth it...

Cool, but im a brake newbie... What is SRF?

ah my bad...Castrol SRF...$70 ish a liter.....

of course there are two boiling points that you'll see on the bottle....

you'll see dry boiling point and wet boiling point....

dry boiling point is what the fluid will boil at fresh out of the bottle....all this is done in a lab of course...

wet boiling point is what fluid will boil at once x% of water has been added.....don't quote me on the amount of water added, somewhere between 1% and 5%...in a lab of course...

Wet boiling point is the important figure of the two....since once we put the fluid in the system, technically it begins to absorb water...

Castrol SRF has the highest wet boiling point of all fluids, Motul 600 is up there as well, but not as high as SRF....

SRF is a tremendous track fluid, yes it costs a little more, but when stopping is a commodity, making sure that vapor lock doesn't occur is key....while most folks spend $$ on HP, brake fluid is one of the first safety measures that must be taken...

so, use up the super blue, its a great fluid, but when its time to change out....down the road, flush the system, and throw some srf in.....it is a must for track...i know iknow...$70ish a liter is harsh, but like i said, I want to be sure I stop...(keeps me from wrecking into armco ya know)....

anyway, just some info.....you'll be happy with the superblue, just whenever next time is...pass it on.

here's a link...note the temps are in Celsius...

Great info.
I never mind spending the extra money for safety. I will cost me more in the long run if i half ass it.
I cant wait to get my car on the track.
Im all ready for it :buttrock

Ja, I notice you have brembo's.....the stock pad that comes with the kit, will not take track abuse....it is a street pad....either made by ferodo or hawk,

it would be advisable to use a track pad.....currently running pagid black front, pagid orange rear....again, the cost is going to be in the $400-$500 range for pads, but you will extend the life of your street pads 10 fold...

Last set of pagid's lasted about 2500 track miles...and the street stock pads that came with the brembo's, have about 20k miles on them, and they are still good as new....

again, a cost upfront, but it will save money over the long term...just thought i'd add that.

Steve,

SRF is OVERKILL for a street car that sees a little track time (99.9% of people on this board). I really can't emphasize that enough.

This is really a race-only part. I've never had a problem running superblue on the track w/ r-comps running full out (within reason). If someone on this board can boil superblue on a street based car, I'd be amazed.

SRF would be great if it were in the $20/liter price range (twice as much as superblue/typ 200) but at $70/liter, its just rediculous.

I'd be spending my money on S.S. lines and pads before I spent $70 on a liter of brake fluid.

Just my .02 :wave:

I like the in-between approach (SuperBlue and SRF).
