Show original supplier description
The Prestone AS401 DOT 3 Brake Fluid is a synthetic fluid engineered to provide superior performance beyond standard DOT requirements for all vehicles that call for DOT 3 brake fluid. Its formulation boasts a higher dry boiling point than the minimum DOT standard, offering crucial protection against overheating, brake fade, and performance degradation caused by water absorption. This fluid also extends its life to 50,000 miles while actively preventing corrosion of all metal parts within the braking system. Designed for versatility, this fluid is safe for use in all DOT 3 braking systems, including those with ABS, disc, or drum brakes. It is also compatible with any other DOT 3 fluid, offering flexibility during maintenance. While Prestone AS401 is recommended to use the specified DOT fluid for your car, this synthetic fluid can be mixed with conventional DOT 3 brake fluid without issue. Packaged in a 32 oz plastic bottle made of HDPE, this brake fluid is a practical choice for complete flushes or topping off. The product information also highlights its use in clutch and brake systems, underscoring its broad applicability.
