BEND EM!

Any old smooth post canti pads fit in place of the four-dot holder. I’m using KS thin line pads for front & rear on 2/5 of the MAFAC equipped bicycles in our household.* Primarily because I had a pile of them and the KS four-dot replacement blocks aren’t inexpensive. Additional bonus, the thin line pads have some toe-in built into their design.

*All bent, none broke.

The rat-tail file trick works as well if you’re patient. Search around on the forum for links and descriptions as to where to purchase bulk alloy washers that’ll fit if you want to make your own without modifying the originals or spending beaucoup bucks at Rene H.
