brakes function more effectively
brakes fail completely
brake operation is delayed after depression of the brake pedal
vapour locking has no effect on brake performance
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
brake drags
brake fades
vapour locking occurs in the brake lines
antilock braking system malfunctions
