1-2 miles around the track. I could stroll around the paddock if that would help.

How often do you hit ABS?

A lot but getting better ;-)

ABS heats up the pad significantly and if you're constantly on it with minimal cool down time, that heat gets transferred to other components in your brake system. Cut down on the ABS engagement since you should pretty much know when it comes on now and your braking performance should be more consistent. :thumbup:

Anyone had this gel up in the reservoir?

Details please!

Only thing I can figure is the tech contaminated it somehow when I had it done at a shop. I sucked out the reservoir, filled with fresh, sucked that back out, filled fresh again, then bled the whole system out with fresh.

I'm glad that this about a DOT 4 brake fluid as I checked with Scion about changing fluids and the following was their response.

Subject Modifications affect on warranty Discussion Thread Response Via Email (Brett K.)05/12/2014 04:48 PM We apologize as we do not recommend or assist with modifying our vehicles from the original factory specifications.

Scion's warranty covers repairs and adjustments needed to correct defects in materials or workmanship of any part supplied by Scion.

Customer By Web Form (Mr. Blank)05/10/2014 06:55 AM My question is what affect on my warranty would changing my brake fluid to a DOT 6 brake fluid have? I would like to have better than stock brake fluid in my vehicle and the service contact at the dealership suggested that it might impact my warranty should I change my brake fluid."


I like to do my research first and the recommended DOT 6 isn't to be found. I still wanted to know what Scion's thoughts were.

I'm not familiar with any DOT6 fluids...

That's what I said, but if you google it, there is a DOT 4 Class 6 fluid.

That is still a DOT4 fluid.

Please reread the last two sentences of my comment. My thanks to CSG David.

DOT 4 brake fluid is a base requirement/specification that the type of brake fluid must meet. In other words, the DOT 4 requirements are actually quite low, hence why you can find DOT 4 brake fluid in your NAPA or Autozone store. In fact, those are not bad if you want some "upgrade" to your daily, however, the differences of quality is key. DOT in North America follows a FMVSS standard while the rest of the world follows the ISO standards.

Here is what someone summarized regarding the "Class 6" requirement:
http://www.jaguarforums.com/forum/ge...ss-6-a-100370/
ISO 4925 class 6 addresses brake fluid with low temperature viscosity requirements for ABS and traction control systems. It also addresses chemical compatibility with two specific newer seal materials.

The viscosity of such a brake fluid at -40C is in the range of 750 cST whereas typical DOT4 is in the range of 1500 cST.

The ISO 4925 Class 6 standard for "Super DOT4" is a good one and thus, ATE SL.6 was formulated. Is it better than other brake fluids? Depends. They are all designed with a purpose in mind and every single brake fluid has a specific range of application. The purpose for this "Super DOT4" is meant for a better ABS response in low temperature regions. Some reports saying it's 30% more responsive, but 30% responsiveness is a vague quantitative value...significant, but vague. Qualitative is another subject which is extremely subjective.

For our purposes and many others with a larger application range they are seeking, Torque RT700 is a great brake fluid to work with. We have quite a stock of RT700 so please do not hesitate to contact us for the brake fluid alongside a set of pads you may be seeking for your application. :thumbup:

Two questions:


1 - I am due to change my BF in my DD (35k miles), and I have a few quarts of ATE super blue that is a few years old (never opened).
Can I use that to push out the old stock BRZ fluid (are all DOT4 BFs compatible with each other)


AND


2 - Regarding having the absolute highest boiling point of BF in a race car.
I was told by a brake expert at driver's school that you will ruin the piston seals in brakes at 400deg ( I assume he meant 400F).
So if that is the case, wouldn't we WANT the fluid to boil and let you know you are cooking the calipers BEFORE you destroy the seals?
Just curious.


Seems to me that IF you boil ANY of the fluids in the chart on page 1, you have already ruined the seals....
