Product Features: - Maintains braking performance for a longer duration thanks to its higher boiling point and the ability to sustain this high boiling point under intense operating conditions. This significantly reduces the formation of vapor lock at high temperatures, ensuring superior and longer-lasting braking performance. - Offers more comprehensive protection for metal surfaces—its specially formulated buffer additives keep the pH value within the alkaline range. Advanced additive technology provides all-around corrosion protection for metals such as aluminum, brass, copper, zinc, and tin, reducing leakage and pressure loss. - Features an optimized sealing expansion rate that effectively minimizes leakage caused by seal shrinkage and wear of moving parts due to excessive seal expansion. - Enhances both operational performance and service life. Outstanding thermal stability and oxidation resistance effectively prevent brake fluid degradation and the formation of harmful deposits, ensuring reliable overall fluid life and critical performance. - Possesses excellent cleaning capabilities, efficiently removing residual moisture, oil sludge, and impurities from brake lines, thereby extending the lifespan of the braking system and restoring braking performance to its original condition. Application Scope: Widely suitable for various conventional hydraulic braking and clutch systems, especially in harsh working conditions or where DOT4 brake fluids are recommended. Compared to lower-performance brake fluids, this product offers enhanced protection against “air lock,” providing greater safety. It is ideal for hydraulic braking systems (disc or drum brakes) in power vehicles requiring DOT4 or SAE J1704 specification brake fluids.
