The Endless RF-650 brake fluid is used in Formula 1, WRC and Dakar Rally, yet is still available for the end-user desiring the highest performing brake fluid. RF-650 works as good in a street car as it does in a F1 car. Within the circuit stages where the braking temperatures reach extremely high heat situations not encountered on the street, very stable performance characteristics can be achieved. Thanks to the high volocity and the even viscosity in our fluid the response in the brake system is very fast and precise regardless of the temperature. The low freezing point (-40 ºC) also makes RF-650 perfect for snow rallys. RF-650 is becoming recognized as the highest-spec brake fluid around the world.

Is my go-to fluid for my track car. I’ve tried many others and this is expensive but best heat capacity

This is the best brake fluid I have ever used… about 10-11 track days this year (I lost count at this point) and I have not even felt the need to bleed them. Never boils, it is used in my daily driver as well. The brakes bite hard all day. This is the brake fluid that the Mercedes F1 team uses, the price is the price… it is WORTH it and more. I don’t know why all performance car manufacturers don’t add this brake fluid to their cars.

Provides firm pedal on bleed.Provided least softening at higher temps, important for brake feel, and critical for clutch release to avoid damaged syncros, dogs, dog rings during hot operation when the clutch needs to keep releasing 100%.

I’ve used a variety of different brake fluids for my track car, including Castrol SRF, and I think I am going to switch to Endless full time. I’ve had zero fade with this brake fluid, and the pedal is so much firmer than it has been with Castrol. My car’s about 3,200lbs and very heavy on the front brakes, so I’ve been really impressed with how the Endless has held up. If you’re not reaching boiling point with the SRF, I’d give this Endless a try.

This was my first time purchasing Endless RF-650 and while it is definitely on the expensive side but you’d be hard pressed to find a better high performance brake fluid. This stuff is really that incredible. It’s less hygroscopic than comparable products which means longer service life and less time spent bleeding/refilling your braking system. I’ve never experienced any overheating or boiling using this fluid and it also provides a wonderfully firmer pedal feel that is consistent over an entire track session. There’s a reason why this is Porsche Motorsport’s choice for factory fill and why you’ll find it in Formula 1 cars as well!

Added to Evo IX restoration project along with rebuilt OEM calipers and new pads/rotors and system is working great!

It’s hard to justify spending this much on brake fluid in a daily driver, but I did it anyway because I drive on average 85 miles a day. I really enjoyed the small but definitely noticeable increase in fluid compressibility, giving me a harder brake pedal.If I had a track car, this is the only fluid I would trust.
Weeeeeeeeee –
It just feels more solid. Highly recommend
