MOTUL RBF High-Performance Racing Brake Fluid – 600 / 660 / 700

Elevate your braking performance with the MOTUL RBF (Racing Brake Fluid) series — engineered for high-performance driving, track days, and full-blown motorsport use. Available in three formulas — RBF 600, RBF 660, and RBF 700 — each option offers increasing levels of thermal resistance to suit your vehicle’s demands and driving style.

These 100% synthetic, DOT 4-based brake fluids are developed to withstand the extreme temperatures generated under hard braking. Whether you’re attacking corners on a mountain pass, hitting apexes at your local circuit, or competing in professional motorsport, there’s an RBF formula designed to keep your brakes consistent and fade-free.

These brake fluids come in 500ml bottles. Please add the appropriate quantity to your basket to cover the amount required. Most vehicles typically require 2-3 bottles per brake fluid flush. If you’re unsure please get in touch.

Installation

Due to safety reasons we recommend any form of brake fluid flush, testing or upgrade be done by a professional.

We’re happy to offer this service at our workshop here in Poole, Dorset. For a quotation and lead time, please get in touch with your vehicle details to discuss further.

Compatibility:

Suitable for all performance cars with DOT 4 braking systems, including vehicles using steel, carbon, or ceramic brakes.

Please Note: 

• Do not mix with DOT 5 or silicone-based brake fluids.
• Always use brake fluid from a sealed container to avoid moisture contamination.
• Brake fluid is hygroscopic — it absorbs moisture from the air over time. It’s recommended to replace the fluid at least once a year for optimal performance.
• Dispose of used brake fluid responsibly.
• Keep brake fluid away from painted surfaces — it can damage paintwork.
