Disc brake conversion inside brake drums?

[xlfan]

Does anyone know if there exists such conversions or has anyone tried themselves?

Just curious why you're wanting to do this. If it's because your drum doesn't work that well, that can probly be fixed.

The girl wants to keep the classic look and still have reasonable stopping power.

oops  ....was compiling all sorta info on how to put disc on.  1979 swing arms interchanged/fit with older frames and can easily go disc in back.  front fork change and you have disc in front (1974+)
but then i reread.  you want to hide disc in drum housings?
oh boy....
anything can be engenered and made.  but for the $$$%$$$
either change to disc or make what is there optimum.
good luck....
