Motul DOT 5.1 Brake Fluid - 1/2 liter

The Motul DOT5.1 fluid is a low viscosity formula for modern ABS and DSC systems. BMW recommends low viscosity brake fluid for all chassis beginning with the E60 5-series and everything after the 2006 model year. Low viscosity (LV) is a thinner fluid that works better than a normal fluid in the small channels and passageways in the ABS/DSC pump. Using the heavier fluid will result in a delayed response to ABS and DSC activation and a spongy feel in the brake pedal (only during ABS stops). The Motul DOT5.1 also meets DOT5 levels for boiling points but can also be mixed with DOT4 fluid. DOT4 fluid is still acceptable to use in later cars under racing/track conditions as the fluid will thin out at higher temperatures (Motul RBF600/660 DOT4 have higher boiling points than DOT5.1). But for street conditions the DOT5.1 is better.
