Motul RBF 700 Racing Brake Fluid — Full Synthetic DOT 4, High Dry Boiling Point

Motul RBF 700 Factory Line is a full-synthetic DOT 4 racing brake fluid engineered to maintain consistent, powerful braking at extreme temperatures with a very high dry boiling point (336°C / 637°F).

Designed for competition and high-performance street use, Motul RBF 700 is formulated to resist vaporization and sustain pedal feel where ordinary fluids can fail. It suits hydraulic brake and clutch systems on carbon, ceramic and steel disc setups and is intended for drivers who demand repeatable braking under heavy loads and high temperatures.

How does RBF 700 improve braking performance under racing conditions?

RBF 700 minimizes the risk of vapor lock by raising the temperature threshold at which the fluid boils, keeping compression consistent at the pedal and preserving braking force during repeated heavy stops. This stability helps drivers maintain confidence during long stints or aggressive braking sequences.

• Dry boiling point 336°C / 637°F for extreme thermal endurance
• Reduces formation of gas bubbles that soften pedal feel
• Optimized formulation for consistent hydraulic response lap after lap

Can I use this fluid in both brakes and clutches on road and track?

Yes — Motul RBF 700 is compatible with hydraulic brake and clutch actuators and meets DOT 4 performance standards, making it suitable for track competition and high-performance road cars. It’s effective with both conventional steel discs and high-temperature race discs.

• Approved DOT 4 performance level for street-legal use
• Safe for clutch hydraulics and brake calipers designed for glycol-based fluids
• Works with steel, carbon and ceramic disc systems when manufacturer allows

Are there any fluids or conditions I should avoid mixing with RBF 700?

Do not mix Motul RBF 700 with silicone-based DOT 5 or mineral-based (LHM) fluids; mixing incompatible chemistries can impair sealing, performance and safety. Also keep the container tightly closed to limit moisture absorption, which lowers boiling point over time.

• Avoid mixing with DOT 5 (silicone) and mineral-based fluids
• Store sealed to prevent water uptake and boiling-point degradation
• Flush system thoroughly when switching fluid types to prevent contamination

How should I store and maintain brake fluid for best results?

Brake fluid is hygroscopic and absorbs moisture from the air, which reduces its boiling point and degrades performance. Keep the bottle capped, store in a cool dry place, and replace fluid at intervals recommended for your vehicle or earlier if you track the car frequently.

• Store in original container with cap tightly closed
• Change fluid regularly; more frequent changes if used on track
• Bleed systems properly after replacement to remove air and contaminants

Who is this for? Motul RBF 700 Factory Line is aimed at racers, track-day enthusiasts and owners of high-performance cars who need a DOT 4-compatible brake fluid that withstands extreme temperatures. If you want a full-synthetic fluid with a significantly elevated dry boiling point for demanding brake and clutch applications — both on the track and for spirited road driving — RBF 700 is designed to deliver that thermal stability. Always follow your vehicle manufacturer’s guidance and avoid mixing with incompatible fluid types.
