ABRO Original Heavy-Duty Brake Fluid DOT 4 (500ml) is a glycol-ether-based hydraulic fluid designed for vehicle braking and clutch systems. It meets DOT 4 specifications and provides reliable braking performance, high-temperature resistance, corrosion protection and lubrication of internal brake components. It is suitable for cars, SUVs, pickups and light commercial vehicles that require DOT 4 brake fluid, including both disc and drum brake systems. It can also be used in hydraulic clutch systems that specify DOT 4. It is generally compatible with DOT 3 systems where the manufacturer permits it, but must never be mixed with silicone-based DOT 5 fluid. For safety, always follow your vehicle manufacturer’s recommended brake-fluid specification and replacement interval.
