PURPOSE: A secondary parking brake device a foot brake device, using fluid pressure is provided to use fluid pressure supporting the parking brake device. CONSTITUTION: A secondary parking brake device a foot brake device comprises a flow path controlling unit(800) and a lever(795). The flow path controlling unit is formed on a flow path(310) between a wheel(500) and a master cylinder(300). The lever operates a cable(790) connected to the flow path controlling unit. A one-way flow path and a two-way flow path are branched into two. A flow path directional valve is formed on the area where the one-way flow path and two-way flow path are branched. A check valve is formed on the one-way flow path and guides fluid toward the wheel direction. |
