Description
Motul DOT 5.1 High Performance Brake Fluid
Upgrade your vehicle’s braking fluid with Motul DOT 5.1, a high-performance synthetic brake fluid developed for hydraulic brake and clutch systems. Its DOT 5.1 formulation is designed to provide reliable performance across a wide range of operating temperatures while maintaining excellent fluidity for modern braking systems.
Motul specifically designs DOT 5.1 for hydraulic brake and clutch systems requiring DOT 5.1, DOT 4 or DOT 3 fluids, with the formulation particularly suited to vehicles equipped with anti-lock braking systems (ABS).
With a dry boiling point of approximately 270°C / 518°F and a wet boiling point of 185°C / 365°F, Motul DOT 5.1 provides a useful margin against brake-fluid boiling during demanding braking conditions. The wet boiling point is particularly important because brake fluid absorbs moisture over time, which can reduce its boiling point.
Designed for ABS Systems
Motul DOT 5.1 has low-temperature viscosity characteristics specifically suited to modern ABS systems. Motul’s technical documentation lists viscosity of approximately 820 mm²/s at -40°C and 2.1 mm²/s at 100°C, helping maintain fluid circulation through the small valves used in anti-lock braking systems.
The formulation is also designed to be neutral with braking-system seals and provide corrosion protection.
Long-Life Brake Fluid
Unlike simply selecting a fluid based on its DOT rating, brake-fluid condition is also affected by moisture absorption during service. Motul describes DOT 5.1 as a long-life brake fluid, with the high wet boiling point intended to provide longer service performance than conventional lower-specification brake fluids.
Motul recommends changing the fluid at intervals of approximately 12–24 months according to the vehicle manufacturer’s recommendations, with annual replacement recommended as a safety measure.
