装有液压盘式制动器的摩托车,其制动液贮存器的上盖固定螺栓,经长时间雨淋或冲车后,常常会造成锈死,而无法卸掉上盖加注制动液。现介绍一种简单的预防方法: 将固定螺栓拧出,将其擦上一层机油后拧紧固定好上盖,再将熔化后的蜡烛油灌满螺栓与上盖之间的缝隙。由于螺栓外露部分被蜡烛油封住,就再也不会锈死了。 Motorcycles equipped with hydraulic disc brakes and their brake fluid reservoir cover fixing bolts, which often cause rusting after prolonged rain or rushing, fail to remove the upper cap to fill brake fluid. A simple method of prevention is described: unscrew the fixing bolt, tighten it with a layer of oil, fix the upper cover, and fill the gap between the bolt and the upper cover with the melted candle oil. As the exposed part of the bolt is sealed with candle oil, it will never rust to death.
