Prestone Synthetic Brake Fluid


Our first DOT3, however this is still a pretty high performance fluid with a number of useful features. The main draw is the anti-vapor capability designed to stop dangerous gas vapors building up in the braking system tubing during high temperatures. 

As a DOT3, this fluid does have a lower boiling point than a DOT4 classified fluid. It does however have higher far higher boiling point than many other DOT3 fluids, and is well above the minimum boiling points set by the government.

In that sense then, it is kind of a middle of the road kind of product. It doesn’t give quite the performance of a DOT4, however it is far superior to a lot of the other DOT3s on the market. Price wise it’s also midrange, for a generous 32-ounce bottle.
