Abstract
To obtain a hydraulic pressure control unit and a straddle-type vehicle brake system, each of which can answer a request for downsizing. The straddle-type vehicle brake system has a hydraulic circuit that includes: a primary channel through which brake fluid in a master cylinder is delivered to a wheel cylinder; a secondary channel through which the brake fluid in the wheel cylinder is released to a primary channel intermediate portion; and a supply channel that supplies the brake fluid to a secondary channel intermediate portion. In a state where a surface on which a motorof a base bodyin the hydraulic pressure control unit is vertically provided is seen from the front, an opening for a first valvethat controls a flow rate on the wheel cylinder side of the primary channel intermediate portion and an opening for a second valvethat controls a flow rate on an upstream side of the secondary channel intermediate portion overlap a first straight line L, and an opening for a third valvethat controls a flow rate on the master cylinder side of the primary channel intermediate portion and an opening for a fourth valvethat controls a flow rate of the supply channel overlap a second straight line Lthat crosses the first straight line Lat a right angle.
