Purpose and Specifications

MOTUL DOT 5.1 Brake Fluid (100950) is a fully synthetic, polyglycol-based fluid perfect for hydraulic brake and clutch systems in cars, bikes, and trucks requiring DOT 3, DOT 4, or DOT 5.1 specs. This 0.5-liter bottle delivers reliable stopping power with a dry boiling point of 272°C to prevent brake fade during hard driving and a wet boiling point of 185°C for long-lasting performance even after absorbing moisture.

Its low viscosity at -40°C ensures smooth flow in cold weather and quick response in ABS, ESP, and ASR systems, making brakes react faster and safer. Neutral on seals and anti-corrosion, it protects your braking components from wear.

When to Use / Replace?

Use MOTUL DOT 5.1 when your vehicle manual calls for DOT 3, DOT 4, or DOT 5.1 fluid, especially in modern cars with ABS for better precision. Replace every 12-24 months or 30,000-50,000 km to maintain peak braking, as brake fluid absorbs moisture over time, lowering its boiling point and risking vapor lock.

Store sealed in a cool, dry place for up to 3-5 years shelf life. Always fully replace, don't top up, to avoid mixing old contaminated fluid.

FAQ

Can I mix MOTUL DOT 5.1 with DOT 3 or DOT 4? Yes, it's fully miscible with DOT 3, DOT 4, and DOT 5 fluids for easy transitions, but full replacement is best for top performance.

Is it safe for ABS systems? Absolutely, its special low-cold viscosity flows easily through tiny ABS valves for instant brake response in emergencies.

How hot can it handle? Up to 272°C dry for track days without fading, and 185°C wet to stay effective longer than standard fluids.
