AMSOIL DOMINATOR DOT 4 Synthetic Racing Brake Fluid
The extreme pressure and high heat common to brake systems can push
brake fluid beyond its boiling point, causing it to vaporize or
"boil-off." Water contamination can accelerate the process. This leads
to a spongy or unresponsive feeling in the brake pedal (vapor lock). In
contrast, the unique chemistry behind AMSOIL synthetic brake fluids
increases boiling points well beyond DOT standards, even when
contaminated with 3.7 percent water. AMSOIL Brake Fluids maintain a
stable viscosity over a wide temperature range and flow easily at the
high pressures generated in today's automotive brake systems to deliver
solid, reliable braking. A nitrogen blanket is added to each bottle
during manufacturing to purge moisture and ensure the maximum level of
performance.
