Iveco Zeta 109-14制动缸（校正）

Hello, a lot of time without going through here, I have a problem with one of the brake master cylinders, specifically that of the rear axle, these cylinders go along with their corresponding lung, said cylinder drip me, I am trying to look for a spare one, I get cylinders with different caliber, there is also no reference in the old cylinder, I have thought about disassembling the cylinder and measuring the internal caliber, but I would have the internal口径。将其安装起来，因为我必须与卡车一起工作，备用时间大约需要10天才能到达。我说我的卡车是iveco Zeta（109-14）

我已经解决了它，用口径拆卸圆柱体和介质，踏上相应的和功能。
