Motul RBF 700 Factory Line – Synthetic DOT 4 Racing Brake Fluid

Motul RBF 700 Factory Line is a top-tier, 100% synthetic DOT 4 brake fluid engineered for extreme motorsport conditions. With an exceptional dry boiling point of 336 °C and a wet boiling point of 205 °C, it delivers consistent pedal feel and pressure stability during long stints, repeated heavy braking and high-temperature operation on steel, carbon or ceramic brake systems.

Key Advantages

• Extreme boiling resistance: 336 °C (dry) / 205 °C (wet) reduces vapor lock and fade in endurance racing.
• Stable viscosity and compressibility: precise ABS/ESP modulation even when brakes run hot.
• Motorsport-focused formulation: ideal for GT, time-attack, drift and pro-level competition.
• System compatibility: usable in hydraulic brake and clutch systems requiring DOT 3/4/5.1 performance (do not mix with DOT 5 silicone or mineral LHM).
• Chemical stability: robust resistance to moisture uptake helps maintain performance over time.

Applications – Track, Endurance and JDM Performance

Recommended for performance-oriented Japanese cars such as Honda Civic Type R, Integra DC5, S2000, Subaru WRX/STI, Mitsubishi Lancer Evolution and Nissan 370Z. Perfect for track days, sprint/time-attack and endurance where thermal headroom and repeatability are critical.

FAQ – Common Questions about Motul RBF 700

What’s the difference between RBF 700 and RBF 660?

RBF 700 has a higher dry boiling point (336 °C vs 325 °C) and is tuned for longer stints and pro racing. Both share the same 205 °C wet boiling point.

Is RBF 700 suitable for street use?

Yes. It meets DOT 4 and works with ABS/ESP. Its benefits are most noticeable in high-heat, track-focused setups.

How often should RBF 700 be replaced?

For track cars: every 6–12 months or after each racing season. Polyglycol fluids absorb moisture over time, lowering the wet boiling point.

Can I mix RBF 700 with other fluids?

Compatible with polyglycol DOT 3/4/5.1 fluids, but for maximum performance perform a full system flush and refill with RBF 700 only. Do not mix with DOT 5 (silicone) or mineral LHM.

Is RBF 700 compatible with ABS and ESP?

Yes. Its viscosity and compressibility characteristics support precise pressure control in modern ABS/ESP systems even at elevated temperatures.
