Motul RBF 660 Factory Line Racing Brake Fluid High Boiling Point DOT 4 – 500ml

RBF660 is a 100% synthetic racing brake fluid from Motul which meets DOT 4 specifications. It features a very high boiling point which makes it suitable for use in the most extreme racing conditions including heavy and powerful race cars using Carbon or Ceramic brakes.

500ML

STANDARDS FMVSS 116 DOT 4 SAE J1703 / J1704 Extreme thermal resistance and stability: MOTUL RBF 660 FACTORY LINE very high dry boiling point (325°C / 617°F) exceeds the requirements of the standards DOT 5.1 non silicone base (260°C mini / 500°F mini) and DOT 4 (230°C mini / 446°F mini), and therefore enables effective braking even in extreme conditions. Allows better aerodynamic performance by reducing the need for brake cooling air scoops on vehicles. Efficient when rainy: MOTUL RBF 660 FACTORY LINE very high wet boiling point (205°C / 401°F) is superior than the requirements of the standards DOT 5.1 non-silicone base (180°C mini / 356°F mini) and DOT 4 (155°C mini / 311°F mini), and therefore enables to keep efficient braking in wet conditions. 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 increases the risk of “vapor lock” phenomena. 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. RECOMMENDATIONS Drain interval: always according to manufacturers’ recommendations and to be tuned to your own use. Avoid mixing with lower performance polyglycol-based brake fluids.
