Series 600 Racing DOT 4 Brake Fluid (BF4) AMSOIL Series 600 High-Performance DOT 4 Brake Fluid is formulated with the best zinc-based anti-corrosion additives and pH stabilizers. Brake fluids fail either because they boil 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. Their higher boiling points make DOT 4 fluids appropriate for high-performance cars and motorcycles and for vehicles used for towing or in mountainous regions. |
