DOT 4.0- Approved for highway use.

AP Racing PRF is currently one of the most popular brake fluids at the highest levels of professional auto and motorcycle racing.  PRF was specifically developed for coping with extraordinary temperatures, such as those encountered when running a carbon/carbon brake system.

Although PRF isn't advertised with the absolute highest boiling point numbers on the market, independent laboratory testing and trackside data collection have confirmed that AP PRF outperforms competing products when temperatures rise.  Don't trust overinflated numbers slapped on a label, trust the product that has delivered countless victories at all levels of racing.

When switching your fluid to AP Racing PRF, Essex recommends purging all of the old fluid from the system via a manual bleed.  Most of our customers find that three bottles of fluid is enough to completely replace their existing brake fluid, and have enough left over for a bleed at the track to remove any remaining air bubbles.

'Typical' New Dry Boiling Point - 320°C (608°F)
