Motul RBF660 Brake Fluid
The Motul RBF660 works at the highest braking temperatures. RBF660 has a high boiling point and is suitable for GT racing cars and vehicles with carbon or ceramic brakes as well as those with limited cooling. If you buy multiple bottles the price of the RBF660 is discounted compared to buying single bottles.
- Very High Dry Boiling Point
What can we say about the Motul RBF660 brake fluid. Its one of our favourite race brake fluids at the moment. Its better than Castrol SRF brake fluid when fresh and is significantly cheaper. The Castrol SRF fluid outperforms with a higher wet boiling point but when you understand what this is we think you will move to the Motul!. The brake fluid wet boiling point is defined as the temperature brake fluid will begin to boil after it has absorbed 3.7% water by volume. Generally brake fluid will reach this level of water volume after roughly 2 years of service. Race and trackday cars tend to be serviced far more regularly due to the higher braking temperatures the cars experience. Fresher brake fluid will always outperform even the best race brake fluid thats been used significantly.
If your braking system still overheats with this fluid and you are unable to run brake ducts or thermal backing plates - we recommend stepping up to the RBF700 brake fluid which has a dry boiling point of (336C)
In summary the Motul RBF660 has a very high dry boiling point of 617F (325C) and a great wet boiling point of 400F (204C). The Motul RBF660 race brake fluid will work in all types of hydraulic brake and clutch actuators requiring non-silicone synthetic fluid. Its specially designed to resist extreme temperature generated by racing brakes. For high performance road cars and track cars where braking temperatures are not as extreme use the Motul RBF600 race brake fluid.
