Prospeed RS683 brake fluid

1/2 liter (500ml)

The best brake fluid money can buy!

You'll usually need just over half a liter to flush an entire car.

Prospeed RS683 was designed with motorsports in mind. Uniquely formulated to be less compressible than other brake fluids at any temperature. This translates to a better pedal all weekend, not just the first few track sessions. This is what we used to win the 2011 Thunderhill 25 hours E2 class and finish 8th overall. Made in the USA.

Track notes

Glycol based brake fluids will naturally absorb moisture out of the atmosphere through the vent in your master cylinder, up to maximum of  3-5% by volume. After being heated severely the brake system will draw in atmosphere as it cools down and contracts. This moisture in the fluid will have a very low boiling point of 210F, causing air bubbles and pedal sponginess when the system gets hot again. Ideally, you bleed the brakes after every track event to get the air out and flush completely a few times a year to get all the moisture out.
