Terminal voltage check with a low battery voltage will lead to erroneous diagnosis.

Otherwise, accurate measurements may not be obtained and personal injury may result.
Electrical circuit inspection procedure
While there are various methods for electrical circuit inspection, described here is a general method to check for open and short circuit using an ohmmeter and a voltmeter.

Air bleeding from brake fluid circuit
Air trapped in the brake fluid circuit acts like a cushion to
absorb a large proportion of the pressure developed by
the master cylinder and thus interferes with the full
braking performance of the brake caliper. The presence
of air is indicated by “sponginess” of the brake lever and
also by la ...
