PURPOSE: To provide an inexpensive vehicular brake device permitting to provide small side and lightweight to brake boosters, and reducing the number of parts and maintenance inspection places as the entire device, and facilitating maintenance control. CONSTITUTION: The exhaust pressure chambers 9a, 9b of power pistons 8a, 8b provided on a plurality of brake boosters 5a, 5b mounted on a vehicular brake device communicate with and held to each other through a communicating passage 10. Communication between a communicating passage 11 and the atmosphere through an air breather 11 performs the breather operation for a plurality of the brake boosters 5a, 5b by means of the common air breather 11 to reduce the number of parts and maintenance inspection places in the brake device. |
