AMSOIL Series 500 High-Performance DOT 3 Brake Fluid
AMSOIL now offers Series 500 High-Performance DOT 3 Brake Fluid. AMSOIL Brake Fluids provide superior high-temperature performance in auto/light truck, high-performance, racing and Power Sports applications.
AMSOIL Series 500 High-Performance DOT 3 Brake Fluid is formulated with the best zinc-based anti-corrosion additives and pH stabilizers. It is designed for high-temperature stability, yet flows easily at low temperatures. AMSOIL Series 500 High-Performance DOT 3 Brake Fluid's superior additive package provides lubrication throughout the system and raise brake fluid boiling point to more than 232°C (450°F). It keeps water in suspension, slowing its effects on the brake system. AMSOIL Brake Fluid boiling point temperatures ensures maximum life and reliable braking power even in extreme conditions. AMSOIL Series 500 High-Performance DOT 3 Brake Fluid has a dry ERBP of 274°C (525°F) and wet ERBP of 156°C (313°F). AMSOIL Series 600 DOT 4 Racing Brake Fluid has a dry ERBP of 304°C (580°F) and wet ERBP of 210°C (410°F).
Brake Fluid Maintenance
Brake fluids fail either because they exceed their brake fluid boiling point or because they cease to provide adequate lubrication and corrosion protection. Both reasons for failure are the result of contamination, usually by water or petroleum products.
DOT 3 and DOT 4 polyglycol ether-based brake fluids are hygroscopic, which means they absorb water easily and hold it in suspension, similar to antifreeze. In most climates, moisture seeps into the brake system continuously through the various seals and microscopic pores of the flexible brake lines. This seepage can accelerate as a vehicle ages and there’s almost no limit to how much water the fluid can absorb. By the time brake fluid has been in the system for three years, it can easily reach its wet boiling point. Because this happens gradually, most drivers won’t discover the reduced braking ability until it’s too late.
Many owner’s manuals recommend changing brake fluid every 24 months to remove moisture. Approximately half of all cars and light trucks in the U.S. over 10 years old have never had the brake fluid changed. In addition, Power Sports applications such as motorcycles, ATVs and UTVs require routine brake fluid changes as well.
