Product details

WOL Motul Factory Line RBF 660 DOT 4 racing brake fluid, 500ml, 2 units

High-performance DOT 4 racing brake fluid for demanding braking use, supplied as two 500ml units.

This Motul Factory Line RBF 660 brake fluid is aimed at demanding braking conditions where heat resistance matters. It is a high-performance polyglycol fluid that goes beyond standard DOT 4 requirements, with an extremely high dry boiling point and quick recovery time.

The listing states 617°F dry and 399°F wet, and also notes compliance with FMVSS 116 DOT 4 and SAE J1703 / J1704. It is supplied here as 2 units of 500ml.

Points to check before use

Follow the vehicle manufacturer’s brake fluid recommendations and service intervals.
Do not mix with silicone brake fluids.
Avoid mixing with lower performance polyglycol-based brake fluids.

Why shoppers choose it

Built for harder use where brake fluid temperature can become a concern.
Higher dry boiling point than RBF600 is stated in the source listing.
Suitable when you want a DOT 4 racing brake fluid with clear specification references.
