Respuesta :

The correct answer is C. viscosity.
You can check the viscosity of the brake-fluid with using a voltmeter. You can see that by using the voltmeter and read on it the volts, the bigger the voltage the bigger the moisture in brake-fluid, thus less viscosity.

Brake-fluid condition can be tested visually, using litmus-type test strips and by checking the

A. temperature.

B. pressure.

C. viscosity.

D. boiling point.
