174. The following are major defects:(1) no braking on a wheel because of the poor working order of a component of the mechanical or hydraulic brake system;
(2) a crack that extends to the outer edge of the friction surface or on another part of the drum or disc;
(3) when the brakes are applied, a support or rivet of the brake lining that touches the friction surface of the drum or disc;
(4) a flexible hose that bulges when under pressure;
(5) a fluid level in the master cylinder lower than one quarter of the normal level;
(6) a brake fluid leak along the system, other than oozing, where the brake is applied;
(7) a hydraulic brake control that has to be depressed several times in order to pressurize the circuit;
(8) a hydraulic brake control that reaches the end of its travel within 10 seconds where a moderate pressure is applied;
(9) the travel of the brake control exceeds 80% of the total possible travel; and
(10) a component of the system that is poorly mounted, missing, crimped, damaged, deteriorated or worn out in a way that hampers the good operation of the brakes.
