Tired of bleeding your brakes in-between runs? Getting a soft pedal after 20 minutes of hard driving? Choose the brake fluid that professional race teams are switching over to; Prospeed RS683 Extreme Performance Brake Fluid. As a technical supplier to Andretti Autosport, the Prospeed RS683 brake fluid has outperformed the competition in the labs and on the track, and is now the brake fluid of choice for all Andretti Race Teams is available to you.
So what makes this fluid more special than the competition? To start, Prospeed RS683 boasts the highest dry boiling point in the brake fluid market at 683°F. What is more important and if often overlooked is the wet boiling point and compressibility of the brake fluid (more background information on brake fluid can be found here) this is where Prospeed excels beyond the competition.
Prospeed has a patented manufacturing process that blends the high temperature performance while minimizing fluid compression. Compression is created by when air gets into the fluid during the manufacturing process. Most fluids (even premium fluids) contain 5% dissolved air while Prospeed boasts a miniscule 1% dissolved air. Now that 4% difference might not seem like a lot on paper, but the next time your pedal gets mushy or goes to the floor, it becomes a big deal.
Most brake fluid is hydroscopic (absorbs water) so no matter what you do, water will get into your brake lines. The need for some water absorption is by design, but sometimes you get more than you bargained for when you add fluid or bleed your brake lines. With a very high wet boiling point of 439°F you can be assured that if some additional moisture gets in the lines, the Prospeed RS683 has a wet boiling point that is higher than many competing fluid’s dry boiling points.
Specifications:
Dry Boiling Point 683° F. (361° C.)
Wet Boiling Point 439° F. (226° C.)
High Temperature Stability >1° F. (> .4° C.)

So spend less time in the pits and more time on the track, make the switch to Prospeed RS683, and we promise you will become a believer like we have.
Some other benefits that have been discovered from use of the Prospeed RS683 fluid by Andretti Motorsports has been that the brake caliper seals on their Indy Cars have lasted 30% longer versus their former fluid suppliers product.
