Liquide frein moto MOTUL 101666

Motul RBF 660 Factory Line

MOTUL RBF 660 is a synthetic brake fluid based on polyglycol especially for racing. Suitable for all brake systems (steel, ceramic or carbon brake discs) currently found in racing. Can also be used in conventional brake and hydraulic clutch systems. Outperforms conventional brake fluids on polyglycol (DOT 3, DOT 4, DOT 5.1).

SPECIFICATIONS / STANDARDS:
STANDARDS: SAE J 1703
ISO 4925 FMVSS 116 DOT 4

SPECIAL ADVANTAGES / USE INSTRUCTIONS:
- Miscible with all DOT 3, DOT 4 and DOT 5.1 brake fluids based on polyglycol, but not recommended,
- Extremely high dry boiling point of 328°C compared to other silicone or polyglycol based products allows safe braking even under the most extreme operating conditions.
- Very high wet boiling point of 205°C compared to other silicone or polyglycol based products allows safe braking even under high humidity or rain racing conditions.
- Under racing conditions, brakes are subjected to high thermal stress, therefore MOTUL RBF 660 should be checked at least after every 2nd race and changed if necessary.
- Brake fluid absorbs moisture from the ambient air. This reduces the boiling point. For this reason, MOTUL RBF 660 should only be stored under constant climatic conditions, carefully closed in the original container.

WARNING: Do not mix with silicone-based brake fluids (DOT 5) and special fluids such as LHM. Fluid may attack paint of the vehicle.
