Keeper pins on V brake pads

I go out of my way to fit them correctly.

I had my rear blocks slide out at some lights shortly after installing them without the pins.

Modern inserts aren't as tight as the Mafac/ Weinnman/ Campag inserts of old.

I've had the same thing (only happened on one side). Seemed to be more of an issue with soft compounds.

I've never looked at the mechanics but I figured the pins must be there to prevent the blocks moving about and that some engineering guy far cleverer than me insisted on this design.
