Endless RF-650 Brake Fluid - Explained

Island_370

Sorry, but with this I call BS. All fluids are considered non-compressible. How can you back the claim of better pedal feel under any use? Under hard use...I see where the higher dry boil and wet boil will help---but your numbers are barely better than RBF600 by the way...

To me, this is like the claim that spark plug companies made....use ours and gain 5 hp...dyno proven. Sure...any new plug will help. Same here. Any full fluid flush will feel better.

You made the claim, now show me the proof.

Not all fluids have the same hydraulic properties. Its a characteristic called compressibility. We don't have test data to show the differences, but our superiority in this aspect is the reason why Porsche AG now uses our RF-650 in all of their Cup cars (Cup, Cup S and RSR).

All professional race teams are familiar with the concept and highly covet superior hydraulic properties (compressibility).

After Porsche AG made the switch, an interesting thing happened with some cup teams which was eventually shared with Endless. They took delivery of the new cars for the year and ran initial track tests with them, after which, they did their normal routine maintenance including flushing the brake fluid. Most teams weren't already familiar with endless RF-650 and therefore put what they were already used to into the lines. The next time they went on track to do testing, drivers reported inferior brake pedal feel. After bringing the cars back in, and checking lines, they found no air and sent the cars back out, never having solved the issue. Conferred with Porsche Motorsport NA, they were told to use the Porsche race fluid, which is Endless RF-650 re-bottled with a Porsche part number. After doing so, drivers reported the original, superior brake pedal feel had returned.

If you don't believe us, some of the various cup car teams from across America will attest to it

I still find it very hard to believe that you will feel a difference in a street-use car with rubber lines and floating calipers (the sport is a fixed caliper, but the base is a floating caliper). All that slop in the system makes the statement a little hard to buy.

Porsche has the best pedal feel of any stock car I have ever had the pleasure of driving. If a significant fluid performance differential exists, I think Porsche's would be the easiest to notice. But in a car with rubber lines and floating calipers....

But I guess it doesn't really matter. I am not going to shell out +$150 for brake fluid. 1 liter might be able to do it, but I am always more comfortable with 1.5 liters (3 bottles). Nothing worse than over bleeding a corner only to need a pinch more for that last caliper.

With that said, we understand that the RF-650 is a hard sell to street guys (for obvious reasons), price being one of them. That's why we offer the S-Four brake fluid, competitive against the Motul RBF600 and offered at a lesser rate.
