Michael- The bike I rode today (an almost on topic, KOF) has the QR set open in normal use to avoid the "where's the brake gone" surprises. Campy NR, bulged QR lever (late 1970s? In service from early 1980s), Scott Mathouser pads. If set up the normal way the QR would open under firm or lengthy braking.

I have attributed this to a vibration that I don't feel at the brake lever but the brake does feel at the QR lever. This is unique to only one bike of mine, two other Campy/SM padded bikes don't do this. The QR opening up started a number of years ago with no one change in the set up. At first it happened infrequently, then more often.

Being the mechanic that I am I checked every thing out over and over for a while. I decided that no one thing was wrong or a danger and just re set the cable with the QR open. As I run 23mm sew ups on this bike the tire only needs a small assist to pass through the pads when removing it. I have used SM pads for a long time pretty much exclusively and always had squeal issues. I think/wonder if I changed pads if the QR problem would likely change.
