For hard braking in circuits and rallies, we recommend using the highest spec fluid.
In stages such as circuits where the brakes experience thermal load, brake fluid is required to maintain stable performance even at high temperatures that would not occur during street use. RF650 is a high-spec brake fluid that has been used and highly regarded in top categories around the world, including F1, WRC, and the Dakar Rally. As indicated by its dry boiling point of 323°C and wet boiling point of 218°C, it consistently transmits pedal force to the brake system under any conceivable harsh conditions.
Of course, replacing with genuine parts is also optimal for users who engage in sports driving.
Brake fluid deteriorates and experiences a drop in boiling point after 2 to 3 years of use since its replacement. Continuing to use it as is can lead to vapor lock phenomena, so it is recommended to replace the brake fluid at the same time as the brake pads. The "S-FOUR" was developed as a replacement for genuine fluid, considering all possible situations for street use. Additionally, it meets the DOT5 standard (BF5 standard) with a dry boiling point of 295°C and a wet boiling point of 187°C, making it suitable for sports driving as well. This fluid offers excellent cost performance by improving the stability of brake effectiveness and feel at high temperatures while achieving long life for street use.
