That's not really the same, The lack of spring or o-ring rubber band didn't lock up the pedal, pushing it a perceived distance greater than normal did. Similar problems with the rear brake locking up can occur if there's not sufficient free-play above normal resting position if the brake fluid boils and expands - it has to go somewhere and if the pedal can't move, then the pistons will, clamping down on rear disc.

Exactly....a sticky pedal reduces the free-play.

I see them as related because if the brake was dragging it was generating heat....boiling the fluid...makes the brakes lock a lot easier.  Combined with the reduced lever travel it caused a problem in my case.  They locked a lot easier than they should have.

Long and short of it is the fluid didn't have enough pressure to return the pedal in my case.  Result was a dragging brake that locked.  

Not arguing your points.  Is it redundant?  Yes.  Unecessary?  If everything is functioning properly it is.  But that doesn't mean it doesn't serve a purpose.  Or it doesn't work.  

In short millions of bikes have a return spring.  It doesn't hurt anything.

I know someone that installed the wrong lever on his front master.  Bought a 2nd hand race SV that had a Honda (older F4I I believe) master on it.  He put a spare SV lever on it after a lowside and hadn't thought anything of it.  Next session as he was tipping in for a turn he felt the bike start to slow.  As he hit full lean the front end tucked.  He figured there was no free-play and the resultant heat cause them to lock.
