Come on, get real, Kneale and Peter!
Pistons can not extend far enough to drop out of the caliper seals, unless
one forgets to install the rotor. Using the passive pad wear detectors, I
routinely wear my pads down to where the backing plates touch the rotor
ridges. Further, there is no piston "cocking force", tendency for the
piston to cock or jam within the caliper bore. They do get sludged up form
lack of fluid change though.
