Thanks for the update.

So, based on that data, when do you think you'll change it?

It's probably not good forever so at some point you're going to do a bleed/flush.

It's time to do it now; we generally recommend that cars that are driven hard bleed their brakes once a year as a precautionary measure, even if the fluid doesn't seem to have degraded.

It's like doing regular oil changes; you want to keep the fluids in your car fresh.

The fresh fluid makes sense.

You guys track your cars a lot more that we do up here because of winter. I put in Project Mu fluid in the spring before my first track session and I will probably end up with 4 sessions this season.

Doing a full flush next spring is probably a good idea.

Some time attack series or lapping groups up here require fresh fluid ever year just because of how fast some fluid degrades, that's the big reason I can't swallow SRF. I think the next fluid I order will be this stuff.

Fully ¼ of the words on the first page of my main DE club's tech sheet is devoted to the subject of the status of the driver's brake fluid:

ALL CARS will have the brake fluid tested at the track for moisture content. You will be required to provide access to the Master Cylinder when the vehicle is presented in tech. If you are not aware of the location of the master cylinder, consult your owner’s manual or ask the qualified individual performing the Pre-Event Safety Inspection to provide access to it.

...

__ 4. BRAKE FLUID: Must have adequate level and be in good condition. Brakes must be bled during safety inspection. We require that vehicles used for driver's schools have brake fluid NO OLDER than six months in the system. This includes all new vehicles regardless of date of manufacture. Any vehicle failing to pass the on-site moisture content test (>= 3%) or having discolored or obviously old brake fluid will not be allowed on the track.
DATE OFLAST FLUID CHANGE:________________


Failure to pass the test is not uncommon.

Tried RBF600 with AP Racing Sprint BBK at Watkins Glen this Mo/Tu, almost got the best of me a couple of times, never again, purchased RT700

RT700 is really excellent! I've done multiple track days and 5000 miles and it still looks like new at the front calipers!

Even with the best fluid, always consider the 1 year flush interval that the Owner's Manual recommends. DOT3 soaks moisture slower than the DOT4 fluids, but annual changes are still recommended.

I've kept the fluid in my car longer than a year for the sake of 3rd party review. :thumbsup:

Just got back from 2 days of tracking on the NJMP Lightning course. AP Racing Sprint BBK, Torque RT700 and Carbotech XP12 performed flawlessly. There are only two hard braking zones but they require slowing down by over 40 mph. RT700 is the only brake fluid I'll use from now on.

Ordered this morning along with some CR pads for the rear to balance things out a little better.

I did 9 track days this year (48 30-minute sessions) on RT700. AP Racing Sprint Kit, Ferodo DS2500 pads. Worked great - will be using this again next year!

48 sessions on the same fluid?

Yep - braked just as well during the last session as the first one!

Did you bleed them during that stretch of 48 sessions?
