Can disc brakes cause front quick-release to loosen?
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.
