| 摘要 |
The present invention relates to a large car auxiliary brake system which operates a solenoid valve by a simple switch manipulation to introduce compressed air to an air master cylinder, and supplies hydraulic pressure to a caliper attached to an axle housing to brake a rotor of a propeller shaft, thus enhancing the braking performance. This system includes a solenoid valve controlling the compressed air by switch manipulation, an air master cylinder generating hydraulic pressure by the compressed air induced to one side through the solenoid valve; and a caliper performing braking as pads compress a rotor of a propeller shaft by the hydraulic pressure.
