Understanding BRAKE FLUIDS
Is soft viscosity at low temp. such as DOT5.1 makes soft pedal touch feel at circuit ?
No, low temp. viscosity may soft but, will not soften pedal touch at circuit. The fluid temp. during circuit run become over 150℃ and viscosity characteristics at the temp.
range has no major difference from other grades. Also, there is no major interrelationship between fluid’s adhesive (viscosity) and pedal touch.
The pedal touch depend on the moisture absorbed and lower the moisture volume more solid touch and higher the moisture volume softer (sponge like) touch.
