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 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.

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.
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.
