BRAKE HYDRAULIC PRESSURE CONTROL SYSTEM AND STRADDLE-TYPE VEHICLE

To achieve a brake hydraulic pressure control system for a straddle-type vehicle which makes it possible to reduce its size as compared to existing ones. A brake hydraulic pressure control system () according to the present invention including: a substrate (); a motor () which is a brushless motor configured to drive a pump device (); a housing () which is connected to the substrate (); and a detection mechanism () which is configured to detect the rotation state of an output shaft () of the motor (), in which the motor () is disposed in a space surrounded by the substrate () and the housing (), and a bearing () of the motor () is inserted into a concave part () formed in the substrate ().
