Well, this is a new one for me. I have Kool Stop V-brake inserts and this morning the pads were gone on both sides of the rear brake!
My first thought was that that someone had stolen them, but on going back to my appartment I found one on the ground.

The only possible explanation is that someone had removed the attachment pins, and the pads had worked loose. The pads have been on for a couple of months and were properly installed.

Weird huh?

In a worse case scenario if all four pins were removed, the pads might have come off simultaneously in a steep downhill or emergency braking. Could be quite nasty :/

The only time I leave my bike unattended is outside the supermarket, so the saboteurs may well have only gotten half way through their devious plan

Anyone heard of this before?
