bremse ETZ125

Ich will in englisch schreiben als es ist mehr einfach.

I have ETZ125 and I have problem with my brakes.
I changed the pieces but the dust seal (manschette) fitting on the piston are not at the right size.
the piston where the dust seal goes has an outer diameter of 34mm and inside on 32mm

The caliper body has an external diameter of 46mm and inside of 44mm.

One of my german friend living in Berlin tried to find but impossible.

I tried to find help in France but impossible.

Would you have a solution ?

It is a MZ sportstar bought in 3/99 nr SNZ1S0000W4608400

Vielen Dank für Ihre Antwort/Hilfe.

Did you already ask Ente? www.motorradente.de
He has many MZ-parts especially from newer models. And you could also ask him in English (and I guess in French ).
