(2) the level of the fluid in the reservoir of the master cylinder that is lower than one quarter of the maximum level specified by the manufacturer;
(3) the brake fluid leaks along the system, excluding oozing, whether or not the service brake is applied;
(4) a pedal that has to be depressed several times to pressurize the circuit;
(5) a brake pedal that reaches the floor within less than 10 seconds when a force of about 550 newtons is applied;
(6) the travel of the brake pedal that exceeds 80% of the total possible travel; and
(7) a power brake that does not work. When the engine is off, the power brake is not able to assist the driver for a brake application.
