These brake fluids are very popular among drivers that track their MINIs, and other track / race cars.

Motul Racing Brake Fluid is a 100% synthetic fluid for hydraulic-actuated brake and clutch systems. Specifically designed to resist the high temperatures of actuated (steel or carbon) racing brakes and clutch systems. Motul RBF far exceeds the standards of DOT 3 and DOT 4.

Select from the RBF 600 or RBF 660 to see more details.

RBF 600:
Dry Boiling Point: 594°F
Wet Boiling Point: 421°F

RBF660:
Dry Boiling Point: 617°F
Wet Boiling Point: 401°F

From the Mini Owners Manual:

Brake fluid is hygroscopic, that is, it absorbs moisture from the air over time.  In order to ensure the brake system's safety and reliability, change the brake fluid every two years.  Brake fluid is toxic and also damages vehicle paintwork. Always store brake fluid in tightly-closed original containers kept well away from the reach of children. Do not spill the brake fluid and do not fill the brake fluid reservoir beyond the MAX mark. The brake fluid could ignite upon contact with hot engine

Motul RBF 600 is a 100% synthetic fluid for hydraulic-actuated brake and clutch systems. Specifically designed to resist the high temperatures of actuated (steel or carbon) racing brakes and clutch systems.

Motul RBF 600 far exceeds the standards of DOT 3 and DOT 4. The RBF 600 container is filled with Nitrogen to increase shelf life and eliminate contamination while factory sealed.

Typical Dry Boiling Point: 594°F
Minimum Wet Boiling Point: 383°F
Typical Wet Boiling Point: 421°F

Extremely high dry and wet boiling points help prevent vapor lock and brake fade during hard use.

Extreme high performance polyglycol brake fluid. Far exceeds the standards of DOT 4. Each bottle is filled with Nitrogen, increasing shelf life and eliminating contamination while factory sealed. Extremely high dry boiling point helps prevent vapor lock and brake fade during hard use, with excellent recovery time.

STANDARDS: FMVSS 116 DOT 4 / SAE J 1703 / ISO 4925

Extreme thermal resistance and stability:
The very high boiling point (312°C / 594°F), superior to conventional DOT 5.1 non silicone base / DOT 5 silicone base fluids (260°C / 500°F mini) and DOT 4 (230°C / 446°F mini) enables an effective brake even under extreme conditions.

Efficient when rainy:
The very high wet boiling point (205°C / 401°F) superior to conventional DOT 5.1 non-silicone base fluid (180°C / 356°F mini) and DOT 4 (155°C / 311°F mini) enables to keep an efficient brake system when rainy. Indeed, DOT 3, DOT 4 and DOT 5.1 brake fluids have the property to absorb humidity in the air, which reduces their boiling points and increases the risk to get to“ vapor lock” phenomenan. The wet boiling point is measured by humidifying the product with about 3.5 % of water.

Avoid mixing with polyglycols based brake fluid with lower performances. Do not mix with silicone (DOT 5 silicone base) or mineral base fluids (LHM). Store brake fluid in its original container, tightly closed to prevent absorption of moisture. Aggressive chemical product if contact with hands, paint or varnish. If skin contact, rinse thoroughly with water.

Motul RBF660: This is the next step in Brake Fluid. The RBF 660 is a 100% synthetic fluid for hydraulic-actuated brake and clutch systems. Specifically designed to resist the high temperatures of actuated (steel or carbon) racing brakes and clutch systems.

Motul RBF 660 far exceeds the standards of DOT 3 and DOT 4. The RBF 660 container is filled with Nitrogen to increase shelf life and eliminate contamination while factory sealed.

Dry Boiling Point: 617°F
Wet Boiling Point: 401°F

Extremely high dry and wet boiling points help prevent vapor lock and brake fade during hard use.

For all types of hydraulic brake and clutch actuators requiring non-silicone synthetic fluid. Specially designed to resist extreme temperature generated by racing brakes (carbon and ceramic) only allowing a minimal air entrance for brake cooling.

STANDARDS : FMVSS 116 DOT 4 / SAE J1703 & J1704 / ISO 4925

Extreme thermal resistance and stability:
Very high boiling point (325°C /617°F), superior to conventional DOT 5.1 non silicone base / DOT5 silicone base fluids (260°C / 500°F mini) and DOT 4 (230°C / 446°F mini) Enables effective brake even in extreme conditions. Better aerodynamic performance by reducing air entrance for brake cooling for cars.

Efficient when rainy:
Very high wet boiling point (204°C / 400°F) superior to conventional DOT 5.1 non-silicone base fluid (180°C / 356°F mini) and DOT 4 (155°C / 311°F mini enables to keep efficient braking while rainy. Brake fluids tend to absorb humidity from the air, which reduce boiling point and increase the risk to get to “vapour lock” phenomena. The wet boiling point is measured by humidifying the product with about 3.5 % of water.

Avoid mixing with polyglycols based brake fluid. Do not mix with silicone (DOT 5 silicone base) or mineral base fluids (LHM). Store brake fluid in its original container, tightly closed to prevent moisture absorption. Aggressive chemical product if contact with hands, paint or varnish.
