Can disc brakes cause front quick-release to loosen? I just purchased a Yuba Spicy Curry Bosch cargo bike with disk brakes and quick release skewers on both wheels. I haven't had any issues with it so far, in fact, I love riding it, but I have read that using disc brakes with a quick release axle can be dangerous, as the braking force can cause the quick release to loosen and the wheel to fall out. It seems crazy to me. Nobody wants to lose their front wheel riding.

Is the risk overstated? Is it something that only happens with badly designed or improperly adjusted QR/disc setups? I check brakes and tire pressure before every time riding, if I just check the QR as well am I going to be fine?

Would it be safer to just replace the quick release on this particular bike with regular nuts?

I just can't imagine it is a common occurrence, but since I ride this bike with my kid as passenger and share it with my wife, I really don't want to leave it to chance. I am curious to hear from anyone familiar with this particular problem of disc brakes, beyond what is stated in the Sheldon Brown article. Thanks!
Most of the time, a bike wheel spins around the axle. When braking, the axle suddenly wants to spin around the point where the brake caliper is grabbing.

The traditional orientation for a fork dropout, with the opening a little forward of straight down, is such that on a rim brake, these forces pull the axle stubs up into the dropout, and no movement can occur.

On a disc QR fork, this orientation of the opening is a poor choice because the axle stubs want to move in that direction under braking forces. Shifting, or in the worst cases ejection, of the hub can occur. A fairly large number of QR disc brake forks have unfortunately been made that use this orientation. That's a trend that's been changing for a while now, but unfortunately slowly. It is the reason a number of QR disc forks have more forward-oriented openings, which looks funny but eliminates the problem.

Skewers that apply higher amounts of clamping force, such as good quality internal-cam ones like Shimano, counteract this tendency but will not necessarily eliminate it.

Usually lawyer lips are sufficient to make actually losing the wheel impossible, but will still tend to allow the hub to shift if the dropout opening gives it a path to do so.
