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 ΒΊC) also makes RF-650 perfect for snow rallys. RF-650 is becoming recognized as the highest-spec brake fluid around the world.
- Used in Formula 1, WRC and Dakar Rally
- Ability to maintain dry boiling point
- Much stiffer and consistent brake pedal with its superior compressibility characteristics
- Becoming recognized as the highest-spec brake fluid around the world
- Even though RF-650 is marketed as a race brake fluid it can be used in all types of vehicles

I have yet to find a DOT4 brake fluid with a higher temperature limit WET and DRY. I’ve had this in my car for almost 1 year and still pull 140 – 0 MPH braking on a hot day without loss of pedal feel.

To be clear to everyone this is DOT 5.1, not DOT 5 HUGE DIFFERENCE. if you take DOT 3 or 4 you can use this as an upgrade, if you car is new be careful, this fluid is thicker and will activate your ABS sooner if you are not careful. I use it in my new vehicle that has ABS and the pedal feels amazing. if you are not confident in your driving i would recommend using Motuls version of DOT 5.1, it is the thinnest racing fluid on the market designed for ABS. If you are looking at this then you know what it is and who they are, hands down the best fluid in the world.

Is my go-to fluid for my track car. Iβve 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.

By far the cheapest way to improve braking performance and pedal feel Iβve made to any car

Endless is great stuff, use it with confidence. A bottle was damaged in shipping. Customer service from Amazon around the return was uncharacteristically bad. Months later and it still isn’t clear that Im not going to be charged for fluid I sent back.
