Hi, i have a daewoo leganza 1999 with abs and i am rebuilding the master cylinder. When i took the pistons out one small pin fell down and i have no idea where it should be.. it is 24mm in length and 4mm in diameter. i'm going to upload a picture from the workshop manual and hopefully someone can tell me where it should be..
Although I am a big fan of taking stuff apart and fixing, but why don't you find a pick and pull yard and get another MC? I'm sure it would be $20 or so. All Leganza's in the US have ABS, unless it has a manual transmission, which is very rare.
