The present invention relates to a hydraulic power brake (HPB) maintenance system and maintenance method. The HPB maintenance system comprises: a HPB system including a hydraulic pressure supply line and a hydraulic return line connected to a wheel cylinder of a brake assembly installed on a wheel by hydraulic pressure stored in a reservoir inside a vehicle, an oil pump installed in the hydraulic supply line and operated by a motor, an accumulator storing high pressure generated in the oil pump, a relay valve that opens the hydraulic pressure supply line when a brake pedal is operated by hydraulic pressure transmitted from a master cylinder having a brake fluid tank formed thereon, a supply solenoid valve installed between the relay valve and the wheel cylinder, and a return solenoid valve formed adjacent to the wheel cylinder; and a pressurization device and a diagnosis device for maintaining the HPB system.

    본 발명은 HPB(Hydraulic Power Brake) 정비시스템 및 정비방법에 관한 것이다. 본 발명은 차량 내부에 있는 리저버에 저장된 유압을 차륜에 설치된 브레이크어셈블리의 휠실린더로 연결되는 유압공급라인과 유압리턴라인과 상기 유압공급라인에 설치되어 모터에 의해 작동되는 오일펌프와 상기 오일펌프에서 생성되어 있는 고압을 저장하는 어큐뮬레이터와 상부에 브레이크액 탱크가 형성되어 있는 마스터실린더로부터 전달되는 유압에 의해 브레이크 페달 조작시 상기 유압공급라인을 개방시키는 릴레이밸브와 상기 릴레이밸브와 상기 휠실린더 사이에 설치된 공급솔레노이드밸브와 상기 휠실린더와 인접, 형성되는 리턴 솔레노이드밸브를 포함하여 구성되는 HPB(Hydraulic Power Brake)시스템과 상기 HPB 시스템을 정비하기 위한 가압장치와 진단장치를 포함하는 것을 특징으로 한다.
