MOTUL DOT 5.1 Long life 100% Synthetic Brake Fluid
For hydraulic actuated brake and clutch systems - DOT 5.1 NON SILICONE BASE
Application:
For all types of hydraulically actuated brake and clutch systems requiring fluids meeting DOT 3, DOT 4, or DOT 5.1 specifications as per manufacturers’ recommendations.
Fluidity specially designed for anti-locking brake systems (ABS) and other electronic stability programs (ESP, ASR,...)
Key Benefits:
- Long life fluid:
- MOTUL DOT 5.1 high wet boiling point (185°C / 365°F) is superior than the requirements of the standards DOT 3 (140°C mini / 284°F mini), DOT 4 (155°C mini / 311°F mini) and DOT 5.1 (180°C mini / 356°F mini), and therefore enables longer use of this product.
- Indeed, DOT 3, DOT 4 or DOT 5.1 brake fluids have the property of absorbing moisture from the air, which reduces their boiling points and therefore braking safety.
- The wet boiling point is measured after moistening the product with 3% water in order to be representative of the state of the fluid after 1 year of use.
- Perfectly neutral with seals used in braking systems. Anti-corrosion.
- Specially designed for anti-locking brake systems (ABS):
- The viscosity at cold temperature (820 mm²/s at -40°C / -40°F) of MOTUL DOT 5.1 is lower than DOT 4 (up to 1800 mm²/s) and DOT 3 (up to 1500 mm²/s) brake fluid specifications and allows easier fluid circulation and flow through the micro-valves of anti-locking systems for better response of ABS and other electronic stability programs (ESP, ASR,...) requiring quick brake systems actuation.
Recomendations:
- Oil changes: 12 to 24 months according to the manufacturers' recommendations.
- For safety advice, draining once a year is recommended.
- Mixable with DOT 3, DOT 4 and DOT 5.1 NON SILICONE BASE products.
- Do not mix with silicone (DOT 5 silicone base) or mineral base fluids (LHM).
- Store brake fluid in its original container, tightly closed to avoid absorption of moisture.
- Aggressive chemical product if contact with hands, paint or varnish.
- If skin contact, rinse thoroughly with water.
