Claims

[Claims for Utility Model Registration] (1) A pressure chamber formed between a cylinder and a piston is communicated with a supply chamber through a communication passage, and the first movement of the piston connects the supply chamber to the supply chamber through the communication passage. In a vehicle brake system having a two-stage actuation type master cylinder, which supplies hydraulic oil from the supply chamber to the pressure chamber and releases the hydraulic oil from the supply chamber to the reservoir chamber by a second movement of the piston, the supply chamber and the reservoir chamber are connected to each other. A check valve is disposed in the first oil passage, and a relief piston is provided in a second oil passage extending from the pressure chamber, the relief piston being in contact with the check valve. Brake equipment for vehicles. (2) In a vehicle brake device in which a plurality of pistons are provided that press pads against a disc plate, and each piston is connected to a pressure chamber of a separate master cylinder, each piston is fixed to the pad, and one piston slides. A vehicle brake device characterized in that the other pistons also slide due to the movement.
