The Highest Dry Boiling Point Racing Brake Fluid You Can Buy

CMS Performance RF1 fully synthetic Racing Brake Fluid is formulated to provide the highest performance under racing and track-day conditions, where braking systems operate at very high sustained temperatures. RF1 exceeds all DOT 3 & 4 requirements and is compatible with all DOT 3, 4, and 5.1 fluids. (Not compatible with DOT5 or mineral-based brake fluids.)

There is perhaps no single safety system more important in racing than brakes. And no part of that system is more critical than brake fluid. At Competition Motorsport, we got tired of (and a little nervous) using "racing" brake fluid on the track that didn't live up to its claimed performance.

So we did something about it. Manufactured in partnership with Orthene Chemicals, a British brake fluid supplier to professional race teams in Formula 1, WEC, and many other pro series, CMS Performance RF1 Racing Brake Fluid is formulated to maintain consistent viscosity, lubricity, and compressibility at extreme temperatures and line pressures found in racing, track days, and spirited driving.

Bottom line: you can spend more money, but you can't buy higher-performing racing brake fluid!

CMS Performance RF1 Racing Brake Fluid Specifications:

  • Typical dry boiling point: 622° F (328° C)
  • Typical wet boiling point: 399° F (204° C)
  • Exceeds DOT3 & DOT4 standards
  • Individual 500 ml (16.7 oz.) bottles

A Note About Brake Fluid Boiling Points

DOT 4 brake fluid like RF1 is hygroscopic, meaning it attracts water over time sitting in your brake lines and reservoir. At high brake temperatures, this water can boil in your car's brake lines, causing the fluid in the lines to become compressible. That's what you feel when you experience brake fade. This is why the "wet" (aged fluid) boiling point of any brake fluid is substantially lower than the "dry" (brand new fluid) boiling point.

Since time is the enemy of brake fluid performance, the best practice is to replace your racing brake fluid before each track event/weekend. At a minimum, flush it with new fluid at least every three months if you're consistently racing and/or driving at track days. A couple bottles of fluid will flush most sports cars or race cars. It ends up being pretty cheap insurance against learning about brake fade the hard way.
