I thought of this the other night, around midnight, after having lost my battle with rebuilding M3 calipers that I was swapping into my 135 (along with all suspension bits and entire rear subframe. It's going to be a 1M wannabe).

I used my son's 3-D printer to make this sleeve for pressing in the dust boots.

thats pretty cool!
I have the rear calipers awaiting rebuild but now I know what I need to have ready ahead of time. Just need measurements for the rear.

I already made changes to the front piece: made round, smooth internal surfaces and shortened the height by about 30%. The original piece took about 2.5 hours to print so downsizing will help the print time quite a bit.

Désolé de faire revivre un vieux fil, mais je suppose que vous n'avez pas encore le modèle pour l'outil que vous avez conçu. drwillb's user avatardrwillb? Tu veux bien le partager si tu le fais ? Je serais très reconnaissant! Je l'ai fait sans outil une fois auparavant et c'était horrible. J'ai une reconstruction de l'étrier à venir, et je ne veux pas le refaire sans aucune aide!
