I've used ATE Super blue many times with zero problems but I'm not too hard on brakes. I've also used AP600 with no issues as well.

 

The big difference is that the Endless RF650 doesn't change very much in terms of braking feel even at higher temperatures, while most, if not all other fluid I've used previously get progressively softer throughout the day. I'm really happy with it.

 

That is exactly what is going into my car next week...I just got my 3 bottles of Prospeed 683 to flush out the old fluid with.

I have been running Motul RBF660 and it's been great but I have seen lots of race cars running Prospeed so I want to try it out.

 

ATE Super Blue sent me flying off the track at 75 mph. I wouldn't recommend that stuff to anyone who drives on a track.

I've been running the SRF and it's been outstanding. The Endless sounds interesting, but I hope the prices isn't similar to the brake pads........

 

SRF, in our opinion is the best fluid. Unless you change your fluid every track event we feel its the way to go.

We have it on sale for 51.00 liter !!!!!

Price is around $33 for 500ml, so a bit cheaper than the SRF. I find the Endless fluid to be more temp stable than the SRF, which seems to be the same consensus reached by Porsche themselves when they switched to Endless fluid for their Cup race cars.

 

^^ will have to try the Endless stuff...what's the best/cheapest place to source this stuff from? Using SRF now, when it comes time to change def want to consider...

 

I used to buy it from a local store in SF, but it looks like they stopped carrying it. Looks like Vivid Racing has it available for 35.99. It's worth a try!

 

What kind of car were u driving?

 

Does the Endless fluid change how the brake pedal feels?

 

The SRF has a Dry boiling point of 590 degrees a wet boiling point of 518 degrees.

The Endless has a Dry boiling point of 622 degrees a wet of 424 degrees.


As soon as you open a bottle of brake fluid it starts to retain moisture .

If you are changing your fluid EVERY track event ,like Porsche Cup cars and actual race cars the Endless would have the numbers.
I would guess ( please insert opinion here) that after one track event you would reach your "wet boiling point" temp.

If you are not flushing the fluid every event the SRF would have the numbers.

 

Good points.

I have been told by some race teams that for amateur racers they put the SRF in and then only do quick bleeds but never flush for the whole season.

 

I'd like to know why an endless pad should be chosen over a pagid yellow for so much more money from someone who has used both.



996 TT, I was very lucky not to hit anything.

 

It's not as if the brake fluid drops instantly to the wet boiling point after one event. I've gone a full year on the Endless without having any issues on the track without a full reflush. I didn't even bleed the brakes after some events and the brake pedal didn't change for the next event. For DE people, flushing after every event is complete overkill.

For racing teams, you might as well do it since you have the time and $.

 

Which fluid is easier on the seals in the master cylinder?

I've been told that SRF is not easy on the seals and to run Motul RBF660 or ProSpeed 683.
