Sure...lots of things to go wrong.  <g>

Probably not.

It shouldn't.

Could be...

Here's what I would do, assuming the fault is consistent:  Drive the 
car until the brakes are warmed up and dragging.  Then jack up the 
front wheel and verify the fault and location.  In toher words, make 
sure the wheel is really dragging.

Once verified, then while the wheel is dragging, open the bleed screw 
- if the wheel then turns free, it's most likely not the caliper but 
a brake hose, or other fault preventing the fluif from returning.  If 
the wheel still drags, then you likely have a bad caliper.  To make 
sure, check the end float on the wheel bearings once the caliper is 
out of the way.
