Frequently Asked Questions

Can I mix RBF600 with my existing DOT 3 or 4 brake fluid?

Yes — RBF600 is fully miscible with DOT 3 and DOT 4 fluids. A complete flush is recommended for optimal performance, but topping off is safe.

Will this work in a DOT 5 brake system?

No — RBF600 is not compatible with DOT 5 systems. Verify your brake fluid type before ordering.

Why is the boiling point so important?

Higher boiling points prevent brake fade during aggressive riding, track days, or extended descents where brake fluid temperatures spike.

Is this street legal?

Yes — RBF600 meets DOT specifications and is street-legal for any motorcycle with DOT 3/4-compatible brakes.
