I have 1990s Shiman Deore XT cantilever brake pad holder shoes with smooth studs. I believe these are "M Type" cartridges/inserts. The replaceable inserts slide in and are held in place by a screw / grub. They look like this:
I need to replace the replaceable inserts. However, I am having a hard time finding replacement inserts.
Is it possible to slide in "V brake" inserts that are readily available as replacement inserts? For example, could I use the following inserts in the shoes shown above?
Or, are there any other inserts that can work with the Deore XT brake shoes that I have? As a side note, there is corroboration that aftermarket replacements for my brake shoes are hard or impossible to find (see here and here, e.g.).
