Similarly, the piston when extended far out at near full travel will droop,
or cock out of alignment.  Seen that one.
Seen that one maybe, Scott, but IMO likely a wrong conclusion on your part.
The piston is not guided by the caliper bore at all, it is only suspended by
the bore O-ring seal and its face contact with the pad backing plate
surface.  Therefore, the piston could only cock if the pad were to wear out
of parallel with the backing plate surface to a high degree, i.e. a highly
tapered pad.  A most unlikely and self correcting condition, one sufficient
to cause piston contact and jamming within the caliper bore.  More likely,
just a sludged up hydraulic system.  Fix it, it ain't broke!
