lubrication
power transmission
cooling
none of these
a high boiling point
low viscosity
compatibility with rubber and metal parts
all of these
The basic characteristics of a brake fluid is * a high boiling point * low viscosity * compatibility with rubber and metal parts
DOT 4 fluid has a higher boiling point that DOT 3 fluid
DOT 4 fluid has a lower boiling point than DOT 3 fluid
DOT 3 and DOT 4 fluids have the same boiling point, but DOT 4 fluid has a longer service life
DOT 4 fluid is more resistance to freezing than DOT 3 fluid
