<p>PROBLEM TO BE SOLVED: To improve installing performance of a brake pressure control device to a vehicle by installing a control valve to adjust brake fluid pressure applied to wheel cylinders according to a result by detecting a slip condition, in a master cylinder part. SOLUTION: A brake pedal stepping-down switch 23 detects whether or not a driver steps down a brake pedal 22. A solenoid valve 25 to increase/hold/ reduce wheel cylinder oil pressure, performs ordinary brake pressure control by communicating a master cylinder 11 and wheel cylinders 14 and 15 of rear wheels with each other in an A position, and holds brake pressure of the wheel cylinders 14 and 15 in a B position, and communicates the wheel cylinders 14 and 15 and an oil sump 26 of the master cylinder 11 in a C position, and reduces brake pressure. Therefore, size reduction can be attained, and installing performance to a vehicle can be improved.</p> |
