Motul Factory Line RBF 660 DOT 4 racing brake fluid, 3 x 500ml

High-performance DOT 4 racing brake fluid with an extremely high dry boiling point for hard use, supplied as 3 x 500ml units.

This high-performance polyglycol brake fluid is aimed at demanding braking systems where heat resistance matters. It is described as exceeding DOT 4 standards and has an extremely high dry boiling point, which is useful when the brakes are being worked hard.

The listing gives dry and wet boiling point figures of 617°F dry and 399°F wet. It also notes that the fluid meets FMVSS 116 DOT 4 and SAE J1703 / J1704 standards.

Points to keep in mind

• Supplied as 3 units of 500ml.
• Designed as a high-performance polyglycol brake fluid.
• The listing advises against mixing with lower performance polyglycol-based brake fluids.
• Do not mix with silicone brake fluids.
• Drain intervals should follow the vehicle manufacturer’s recommendations and your own use.

For buyers, the main value here is heat resistance and track-style braking performance, but the existing fluid in the system should always be checked before topping up or changing over.
