Motul RBF 660 Factory Line Racing Brake Fluid - Universal - 500ml
Motul RBF 660 Factory Line is a 100% synthetic DOT 4 racing brake fluid for hydraulic brake and clutch systems that need a non-silicone synthetic fluid. Motul designed it for the extreme heat of racing carbon and ceramic brakes, and it suits conventional steel discs and hydraulic clutches too.
Its 325°C dry boiling point gives more margin than RBF 600, and Motul notes it can reduce the need for brake cooling air scoops. Sold as a single 500ml bottle.
Note: Do not mix with silicone-based (DOT 5) or mineral (LHM) brake fluids, and avoid mixing with lower-grade glycol fluids. Brake fluid absorbs moisture, so change it to your car maker's schedule and more often for track use. It is harmful to paint and skin, so rinse any spills straight away. Installation by a professional is recommended.
