Motul RBF 700 Factory Line Dot 4 Brake Fluid 500ml

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

Motul RBF 700 Factory Line is an extreme-performance DOT 4 brake fluid developed primarily for racing and highly demanding motorsport applications, while also being suitable for high-performance road and track vehicles requiring exceptional resistance to brake fluid boiling.

With an outstanding dry boiling point of 336°C and wet boiling point of 205°C, RBF 700 delivers thermal performance far beyond conventional DOT 4 brake fluids.

Designed to maintain braking power, pedal consistency and repeatable hydraulic performance under severe temperature conditions, Motul RBF 700 is ideal for race cars, track-day vehicles, competition motorcycles and other motorsport applications exposed to repeated high-energy braking.

Why Choose Motul RBF 700?

Brake fluid is exposed to extreme thermal loads during competition use.

Repeated high-speed braking can transfer significant heat from the brake discs and calipers into the hydraulic system, eventually causing conventional fluids to approach their boiling point.

Motul RBF 700 is designed specifically to cope with these extreme temperatures.

Key benefits include:

• Exceptional 336°C dry boiling point
• High 205°C wet boiling point
• DOT 4 specification
• Developed primarily for racing use
• Suitable for high-performance private vehicles
• Improved braking consistency under extreme temperatures
• Excellent resistance to vapour lock
• Designed for repeated high-energy braking
• Suitable for car and motorcycle motorsport

336°C Dry Boiling Point

The standout feature of Motul RBF 700 is its exceptionally high dry boiling point of 336°C.

Dry boiling point represents the performance of fresh brake fluid before significant moisture absorption has taken place.

The higher the boiling point, the greater the thermal reserve before vapour can begin to form within the braking system.

This makes RBF 700 particularly well suited to:

• Circuit racing
• Time Attack
• Sprint events
• Endurance racing
• Frequent track days
• High-powered track cars
• High-grip tyre setups
• Motorsport brake systems

For applications where brake temperatures regularly reach extreme levels, this additional thermal capability can help maintain consistency throughout demanding sessions.

205°C Wet Boiling Point

Motul RBF 700 also provides a wet boiling point of 205°C.

Brake fluid is hygroscopic, meaning it naturally absorbs moisture from the atmosphere over time.

As moisture content increases, the boiling point of the fluid falls.

A high wet boiling point helps the fluid maintain strong thermal performance even as moisture is absorbed.

Motul RBF 700's combination of extremely high dry performance and strong wet performance makes it particularly suitable for demanding motorsport environments.

Designed for Racing Use

RBF 700 has been developed specifically with racing conditions in mind.

Competition braking systems can experience sustained temperatures far beyond those encountered during normal road use.

The fluid is designed to help maintain braking performance and consistency during:

• Repeated high-speed braking
• Short cooling periods
• Long circuit sessions
• High-energy braking zones
• High ambient temperatures
• Demanding racing conditions

This makes it particularly well suited to dedicated track and competition vehicles.

Improved Braking Consistency

Under severe braking temperatures, maintaining consistent hydraulic behaviour is essential.

Motul RBF 700 is designed to improve braking uniformity under extreme conditions, helping the pedal response remain predictable as temperatures rise.

For a racing driver, consistency can be just as important as outright braking force.

A predictable pedal allows braking points and pressure to be repeated more confidently from lap to lap.

Helps Prevent Vapour Lock

If brake fluid reaches its boiling point, vapour can develop inside the hydraulic system.

Unlike liquid brake fluid, vapour can be compressed.

This can result in:

• Increased brake pedal travel
• Soft or spongy pedal feel
• Reduced braking consistency
• Brake fade
• Loss of confidence under heavy braking

The exceptional boiling performance of RBF 700 is designed to minimise the risk of this occurring during extreme use.

RBF 700 vs RBF 660

Both Motul RBF 660 and RBF 700 are Factory Line fluids designed for highly demanding braking systems.

RBF 660 offers:

• 325°C dry boiling point
• 204°C wet boiling point

RBF 700 offers:

• 336°C dry boiling point
• 205°C wet boiling point

RBF 700 therefore provides an additional level of thermal capability, making it the more specialised choice for vehicles operating at the highest brake temperatures.

For frequent track days and serious performance use, RBF 660 already offers exceptional performance.

For dedicated motorsport, competition or applications where maximum thermal resistance is required, RBF 700 provides the greater temperature reserve.

RBF 700 vs RBF 600

Motul RBF 600 provides:

• 312°C dry boiling point
• 205°C wet boiling point

Motul RBF 700 increases the dry boiling point considerably to 336°C while maintaining a 205°C wet boiling point.

This makes RBF 600 an excellent choice for performance road and track-day vehicles, while RBF 700 is positioned more heavily toward dedicated track and motorsport use.

Performance Brake System Compatibility

Motul RBF 700 is an ideal partner for high-performance braking components such as:

• AP Racing big brake kits
• XC3 Engineering BTCC brake kits
• Motorsport calipers
• Two-piece floating brake discs
• Racing brake pads
• Braided brake lines
• Brake cooling systems

Brake fluid should be treated as part of the overall braking system.

Upgrading calipers, rotors and pads can significantly increase braking capability, but fluid must also be able to tolerate the heat produced by those components.

High-Performance Road Cars

Although RBF 700 is primarily designed for racing, it is also recommended for high-performance private vehicles where extreme braking temperatures may be encountered.

This could include:

• Highly modified performance cars
• Cars seeing frequent track use
• Fast-road and track builds
• High-powered vehicles
• Cars running semi-slick tyres
• Vehicles fitted with competition braking systems

For normal everyday road use, a less specialised brake fluid may provide sufficient performance.

Motorsport Applications

Motul RBF 700 is suitable for demanding motorsport applications including:

• Circuit racing
• Time Attack
• Clubsport
• Sprint competition
• Endurance racing
• Track-day cars
• Competition motorcycles
• Other high-temperature motorsport applications

Its primary purpose is to maintain reliable hydraulic performance where braking temperatures are particularly severe.

Brake Fluid Maintenance

Even extreme-performance brake fluid gradually absorbs moisture after being introduced into the braking system.

As moisture content increases, its boiling point decreases.

Competition and heavily tracked vehicles should therefore have brake fluid inspected and replaced more frequently than normal road cars.

Keeping the fluid fresh helps maintain:

• Maximum boiling resistance
• Consistent pedal feel
• Reliable hydraulic pressure
• Predictable braking response
• High-temperature performance

Fresh Fluid Before Track Use

For serious competition use, fluid condition should form part of regular brake-system preparation.

Older fluid that has absorbed moisture will not provide the same thermal performance as fresh fluid.

For vehicles frequently exposed to extreme brake temperatures, regular bleeding or complete fluid replacement may be worthwhile depending on the vehicle, braking system and competition schedule.

Professional Installation Recommended

Correct brake bleeding is critical when using any high-performance brake fluid.

Air remaining in the hydraulic system can compromise braking performance regardless of the fluid's boiling point.

Professional servicing is recommended if you are unfamiliar with:

• Brake bleeding procedures
• ABS hydraulic systems
• Big brake kits
• Motorsport braking systems

Important Information

Always check that DOT 4 brake fluid is suitable for your vehicle before use.

Brake fluid is safety critical and should remain free from contamination.

Avoid contamination with:

• Water
• Oil
• Dirt
• Incompatible hydraulic fluids

Brake fluid may also damage painted surfaces, so spills should be dealt with immediately in accordance with the manufacturer's guidance.

Keep opened containers tightly sealed to minimise moisture absorption.
