を取付けたことを特徴とするブレーキ制御装置。 A tandem-type brake master cylinder that pumps brake fluid to a front wheel cylinder and a rear wheel cylinder, and a hydraulic pressure control valve attached to the master cylinder to control the hydraulic pressure of the brake fluid that is pumped to the rear wheel cylinder. The master cylinder includes a housing, a primary piston and a secondary piston movably housed in the housing, a sliding member that slides into contact with the inner surface of the housing as the secondary piston moves, and a primary piston and a secondary piston. and a port formed in the housing between the piston and the hydraulic pressure control valve, and the step moves in response to hydraulic pressure in an inlet chamber connected to the port and hydraulic pressure in an outlet chamber connected to the rear wheel cylinder. a poppet valve that opens and closes a liquid passage communicating between an inlet chamber and an outlet chamber by movement of the piston and the stepped piston;
In a master cylinder with a hydraulic pressure control valve,
A brake control device characterized in that a magnet is attached to either one of the port-side end of the poppet valve and the sliding member, and a magnetic body is attached to the other of the port-side end of the poppet valve and the sliding member.
