Aiming at the problem of the aircraft’〖KG-*2〗s automatic anti-skid brake system polluted easily and leading to the brake failure, through the analysis of existing anti-pollution measure, it was found the brake system had weaknesses in anti-recoil control. Various types of filter material were analyzed, conical metal mesh was chosen as the anti-recoil oil filter material. The prototype was manufactured, and the experiments of normal temperature, low temperature, high temperature, and gas-containing state and life test were conducted. The results show that low temperature and gas-containing state have a significant impact on the forward and reverse pressure shock and the pressure build-up and release time. The function of filter material is normal after the life test, and its performance is slightly degraded.
