ok my last thread failed, so we're just gonna do the simple version of the problem this time:

CLIFFNOTES:
--The right heelpiece of my fks bindings is missing two little plastic "covers"
--The left heelpiece is fine and intact
--The right heelpiece very loose when my boot is out, but it snaps in and skis solid
--Is this a problem? Can it become a problem?

Thanks for any input

the plastic bushings suck on those. just about every pair breaks at the inner bushing, but ive never seen them brake there. either way, they are really just to keep them stationary when they are clicked out. when your clicked in its pressuring the metal cam axle. so you should be ok. but if you do wanna fix it, all you have to do is find some old scrap TTs, and drill out the end of the rivet on the U bar thing, and you can change them. to reassemble, dab a lil epoxy in there. works like a charm

Same thing happenned to me.  Except mine are just chipped/ partially missing on both heels.  First time i noticed it was when it fell off on a jump.

Made for a good sequence i guess but down at the bottom i checked the forward pressure and it was extremely loose on one heel (how idk)  So i just tightened it and since then I have had no problems.  For what its worth i haven't noticed a difference with/ without the plastic pieces

yeah one of mine is missing too and is loose like you said when my foot isn't in, but it skis solid. i noticed it back in dec-jan and i've skied 120+ days on the bindings this year and they still are holdin up fine. though i don't know if its bad or not haha

Hey hey!! bump this with a new question!!! hypothetically speaking, will a 12 din binding set at 10 release easier then a 15 din binding set at 10???

I dont think so, but the 15 DIN binding wouldn't break as easy.

It should be the same. But over time i would believe that it may differ. The only difference is the spring inside the binding is tensioned more/less (idk) on the 12 din binding because is is close to its max. Where on the 15 din binding 10 is right about the middle, which is supposed to be the ideal position for the spring.
I'm pretty sure on that, someone correct me if im wrong though.

DIN stands for dutch industrial norms, and thus, at any given DIN setting the spring tension is the same. whether it be a 15, 20 10000000 din , if you put it a 10 its 10. and since there is no permanent deformation of the spring, it doesnt matter how close or far to the end point you are, it shouldnt make a difference.
im pretty sure, but could be wrong, after all this is physics
