Endless RF-650 Brake Fluid - Explained




From HSPN.com:
Endless RF-650 - The Ultimate Brake Fluid for the Circuit and Rally Category
The Endless RF-650 brake fluid is used in Formula 1, WRC and Paris Dakar Rally, yet
is still available for the end-user desiring the highest performing brake fluid. Within
the circuit stages where the braking temperatures reach extremely high heat
situations not encountered on the street, extremely stable performance
characteristics can be achieved. The RF-650 is becoming recognized as the
highest-spec brake fluid around the world. Endless continues in its 4th year
partnering/supplying the Honda BAR F1 Team and is both currently supplying and
testing with a handful of other F1 teams. This fluid is also standard equipment in all
Porsche 911 GT3 Cup (997) cars. Unlike many other fluids that use a recycled
material in its formula, Endless uses a pure material in its original form.

ENDLESS USA PRESS RELEASE
Response from current victories and events

Endless Equipped Cars Dominate Motorsports Weekend
Huntington Beach, CA (May 28, 2009) – Endless equipped teams across the globe showed their dominance this past weekend of May 23rd and 24th. From World Rally Challenge to the Formula One Monaco Grand Prix to the Nurburgring 24 Hours, all teams clenching victory used Endless as an integral part of their brake package.

Italy was next on the WRC schedule and Ford occupied both the 1st and 2nd place steps on the podium. Ford’s rally cars use the ever popular Endless rally/sprint race brake pad compounds and Endless RF-650 brake fluid.

Brawn GP continued their dominance and further extended their lead in the Formula One championship by finishing one-two at the glamorous Monaco Grand Prix. Yet again Jensen Button and Rubens Barrichello drove their Brawns equipped with Endless RF-650 brake fluid straight to victory lane.

But perhaps the most success enjoyed by Endless and their supported teams was in the famous 24 Hour Endurance race at the Nurburgring. More than forty cars in the field used Endless product for the grueling race. It was a sizable presence of Endless equipped cars; including Mitsubishi Lancers, Nissan 350Zs, and Alpina BMWs. More impressive, however, were the overall 3rd place Manthey Racing Porsche GT3 Cup car, 2nd place ABT Audi R8 and 1st place Manthey Racing Porsche GT3 RSR, all running Endless brake pads and fluid.

“It was a phenomenal weekend for our global Endless group,” said Executive Director of Endless USA, Dominic Chen. “The product truly speaks for itself by means of race victories. We are extremely proud to be working with such high caliber, talented people.” Endless hopes to add another endurance race win when the Texas based Risi Competizione team heads to France in a few weeks time to defend their class victory from last years 24 Hours at Le Mans.

DETAILS AND COMPARISONS:
**Courtesy of Endless USA

Used in the top categories of F1, WRC, and Paris Dakar. Recognized by circuit users worldwide. DOT5 BBF Grade Standard. Especially developed for long endurance races ("24 hours") where extreme high temperature stability is required, but it is suitable for all types of competition. Optimal for maximum heat load conditions unheard of within the street stage. Endless is the official supplier of brake fluid to the Honda Racing F1 Team where the RF-650 is used exclusively in all testing and racing activities. Non-silicone based brake fluid. 0.5 Liter per bottle.



Here’s a graph of boiling points according to water content. Our RF-650 and the AP600 are very stable, with the RF-650 being a bit better. However, the SRF drops off violently when you get water in it. This means you can keep the RF-650 in there longer without having to do a full flush in fear of having water in the system. Water in the system means it’ll boil giving you a spongy brake pedal.




Now the other issue; compressibility. With our RF-650 brake fluid being standard original equipment on all Porsche GT3 Cup cars (Yes. Standard equipment from Porsche.), a lot of various teams in the US have been in close contact with me regarding it. Most have never heard of it before Porsche started using it as an OE part 2 years ago. Most of them had been using Castrol SRF.

What these GT3 Cup car teams have been telling me is that they’d put the fluid in the system, bleed it, and then go out on track. 5 or 10 minutes into the session the drivers would report the brake pedal feeling soft. So, they’d bring the cars in and check for air only to find none in the system. The actual issue ended up being compressibility. In short, different brake fluids compress more than others which accounted for the drivers reporting a soft pedal.

The teams tried a bunch of different fluids before realizing they should try ours (reason being they had never heard of Endless and they didn’t know where to get it). The teams tried AP, Motul, and others even I had never heard of, all still ending up with the same issue. Finally, when the GT3 Cup cars ran at the Formula 1 Grand Prix in Canada, they talked to the F1 teams. What they found out is that there are only two brake fluids used in Formula 1; one being Endless. Turns out the Brembo fluid and ours are the only ones without severe compressibility issues.

It's what's in my brake lines and I couldn't be happier.

So what's the dry and wet boiling point?

It's at a premium to the stuff I use now (Amsoil) at roughly triple the cost, so it better be super good.

I just bought enough motul rbf600 for 3 of my cars, its bp dry is 593, I don't expect anything to really be any higher. If this is sig. more (doubtful) I'll switch all 3 cars to it.

We have added the boiling points to the main post. Let me know if you guys have any questions.

DrivelineSales

iTrader: (181)

Also... Just to add, boiling points are largely similar from fluid to fluid. what differs is longevity (the rate the fluid absorbs water) and the hydraulic properties

goofygrin

iTrader: (5)

Hmm...
Amsoil Dot 4
Dry: 304°C
Wet: 210°C

RF-650
Dry: 328°C
Wet: 218°C

Amsoil:
$14/12oz

RF650:
$35/500ml (16.9oz)

Ya'll can make your own conclusions.

Can you expound on how one fluid's "hydraulic properties" might be different from another?

The rate of water absorption is an interesting one... and I don't think there's enough research into this honestly.

DrivelineSales

iTrader: (181)

In terms of "hydraulic properties", it all relates to compressibility, where one might be more compressible than the other. This can all really be seen under more-extreme conditions (i.e. track events, auto-x, etc).

In terms of water absorption rates, there have been a series notable cases where many professional race teams using Castrol SRF will need to flush (not to be confused with bled) their brake fluid at least twice a season or more, depending on the environment. This is not the case when using the RF-650. The frequency of which the system needs to be flushed is far lower.

In a way, you'll find the RF-650 will last you twice as long as the SRF. After everything the pricing really works out to be about the same between the two, if not better when using the RF-650.

i'm using this fluid. it is incredible.
I have no issues with it at all. Even when i cook my brakes downhill over 8 miles.

Endless really prides themselves on product-longevity. This is something you don't see with most other braking manufacturers. Yes, you do pay more up front with the benefit of paying less in the long run. Just ask any the track guys currently using Endless race pads. Most will all agree that the performance vs. $$$ aspect is far better with any Endless product.

lol, my rotors are all but dead, but my Endless pads are still good and it pains me that I will have to toss them early. (I don't put used pads on new rotors)

DrivelineSales

iTrader: (181)

Sorry to hear about your rotors. To help you out, Dominic from Endless would like to shed some light in reference to what some of the pro's have done:

"Risi Competizione put their used Endless N35S compound on new rotors without any problems whatsoever. They used the same set of pads for 3 separate ALMS races because the wear was so good. Whereas with Pagid, they'd throw away a used set of pads after one weekend even if there was pad material left on them because Pagid's lose their friction levels after hard use for one weekend."

Also under further investigation, we have found some major points showing that the SRF fluids does show to be far more expensive than the RF-650. Combined with FAR LESS consumption, the SRF per liter is about $75.00, whereas the RF-650 is $66.00.
