AMSOIL synthetic brake fluids surpass Department of Transportation (DOT) requirements and provide racers with a brake fluid that delivers superior high-temperature performance preventing brake fade and vapor lock.

Ultra-High Boiling Points
AMSOIL DOMINATOR® DOT 4 Synthetic Racing Brake Fluid features ultra-high boiling-points of 410ºF (wet) and 580ºF (dry). It maintains a low compressibility during the most extreme racing conditions.

*Dry equilibrium reflux boiling point (ERBP)–the boiling point of new, freshly opened brake fluid.

**Wet ERBP–the boiling point of brake fluid having absorbed 3.7 percent water. Only 3.7 percent water contamination is often sufficient to reduce a DOT 3 fluid’s boiling point below the DOT minimum.
