Show original supplier description

The Hawk Performance HP660 is a premium DOT 4 brake fluid engineered for the demands of motorsports and high-performance street driving. It offers significantly higher boiling points than standard DOT 3 and DOT 4 fluids, with a minimum dry boiling point of 608°F (320°C) and a minimum wet boiling point of 383°F (195°C). This racing-specific brake fluid is packaged in a 500ml bottle and is designed to surpass Original Equipment (OE) specifications. Its formulation is ideal for applications where brake system temperatures can become exceptionally high, such as track days, autocross, and professional racing. The high boiling points ensure that the fluid maintains its integrity and hydraulic efficiency even under the most severe thermal loads. When upgrading brake components or preparing a vehicle for track use, the choice of brake fluid is critical. Hawk HP660 provides an enhanced safety margin and improved pedal feel by resisting fluid degradation and fade that can occur with lower-specification fluids. It is a key component in a comprehensive high-performance braking system.
