V4 MOTOR VEHICLE BRAKE FLUID Kunlun V4 automotive synthetic brake fluid is prepared with polyalcohol ether ester lubricant as the base fluid and a variety of excellent additives.It has excellent high temperature resistance to gas resistance and low temperature flow performance.Can pass 24 hours damp anti - rust test And 260 hours of metal corrosion test, so that the metal parts in the braking system do not rust, corrosion, to ensure long-term normal and reliable work. recommended Domestic or imported all kinds of cars, commercial vehicles, off-road vehicles, buses and construction machinery vehicles. Especially suitable for clutch system, brake system. It can replace HZY3, HZY4, V3 or imported DOT 3, DOT4, Super DOT4 brake fluid. Product specification Conform to the standard ▪ QC/T 670-2000 V-4 ▪ GB 12981-2012 HZY4 ▪ USA FMVSS No.116 DOT4 The performance characteristics of High temperature ▪ Equilibrium reflux boiling point greater than 250℃, exceeding DOT4 requirements. Low temperature - Low temperature motion viscosity is less than 1300mm2/s, better than DOT4 requirements, ensure the braking sensitive and reliable.Anti-rust ▪ It has unique anti-rust performance and can pass 24 hours damp corrosion test of cast iron. Corrosion resistance - Corrosion test is extended from 120 hours to 260 hours to improve the metal protection ability.
