A friend of mine is going to get her 2006 911's brake fluid flushed. The shop that she's having some other work done quoted her around $90 for a quart of brake fluid. (She couldn't remember which brand it is.)

Is there any reason ATE Super Blue wouldn't be compatible with her 911? The tracks she be doing DEs on are pretty easy on brakes. Thanks for the help.

They are 'hopefully' quoting Castrol SRF which retails for a bout 75/bottle most places. I know on at least some the factory racecars they have the 'only use' sticker on them but not sure about the street cars.

SRF has a really good wet boiling point so if you rarely bleed your brakes it can be a good thing. However if you do bleed them regularly I find it to be a large expense when fluid like Super Blue will do just as good of a job.

Pegasus has a good compatability chart http://www.pegasusautoracing.com/gro...pID=BRAKEFLUID

I try to avoid ATE Blue simply because the blue dye eventually colors the plastic reservior. I agree that $90 should be Castrol SRF.

If your friend is not going to track her car then Porsche fluid is fine and is and is only $22 a quart. I use Motul600 fluid and it is only $36 a quart. Castrol SRF is not needed for the street but it is the most expensive fluid at $74 a quart.

ATE also makes a "gold" product that is supposed to be chemically identical to the blue. It is a great value and I use it in all my cars.

I always rotate between the ATE blue and their gold product - sure does make flushing easier. In my searches here I saw some people state that it can't be used in Audis for some reaon. So other than the boiling points, there's no specific reason not to use ATE in her Porsche? That's what it sounds like but just double confirming.

That's a great chart on the Pegasus site!

Thanks for the link and info.

IMO, if the rest of the car is stock (i.e., stock pads, stock rotors, street tires, etc), then running Castrol SRF might be overkill at this point.

For street driving, it does allow you to go longer between flushes - but for track driving you should be maintaining your fluids more often, which makes SRF an expensive option unless your car is "past stock." ATE or Motul will be just fine and the cost will make more frequent flushes palatable.

I would hope that 90 is SRF and while most likely over kill It is the goods. I never like the feeling of the brake pedal with super blue in a newer car so If you want to save money use Motul like i do

Hey Gran Racing,

Great book - thanks!

FWIW, a customer had HORRIBLE problems with his Cayman S warranty coverage because of the "unapproved brake fluid" - ATE Blue.
A nightmare. FWTW.

I also don't like the staining and besides Motul RBF600 is quite a bit better. WIth slight age, it seems to change from a very light amber to a darker color quite readily which, for me, makes fluid changes pretty easy to identify.

Thanks.

Craig, could you please explain "wet boiling temp" and "dry boiling temp"? Since brake fluid is obviously a wet fluid, what does the wet and dry refer to?

TrackDays247.com

The point at which a fluid boils with a set amount of H2O suspended in the brake fluid itself.

Dry: Fresh fluid, no water
Wet: Represents fluid with the fixed amount of water within fluid. Roughly approximates old brake fluid -

Some examples of usage based on a few thousand customers:
1) GT3/997GT2/997TT - Motul RBF600 is usually just fine. SRF usually overkill.
2) 996TT used hard on track - Motul RBF600 AT A MINIMUM. These are problem brakes when used hard....bee-lieve it or not.
3) Base 996/997: Used hard, Motul is a minimum requirement.

Most find that Motul RBF 600 represents a fantastic value and works well in about 90% of all Porsche brake situations/usages.

Questions? E-mail me rennstore@comcast.net or post here

I'm in that small 10% (I have a 996). I was running Motul 600 with these.




Now I run SRF with these.

Wet boil point is measured at 3% water uptake.
