On my cross bike, I went to the smaller road sized pad on the front and the fork stopped shuddering when I braked.

I was hoping to do the same on my commuter. I will be using the longer canti pads (that used to be on the front of my CX bike) in the rear.

I can scrounge all of the washers off an old set of non-cartridge pads.

I was hoping somebody else managed this conversion already. I may just spend the $20 and be done with it.
