Yesterday I wrecked my left MTB pedal (Shimano 959) on the P.R. The rear, sprung part became loose, clattering and useless, but I was able to ride out using the other side. I think I hit something, pulling back that sprung piece until it let go.
Things brightened when I looked closely at it at home. No parts were lost, and I was able to fish out the tension screw with pliers. I couldn't get it reinstalled until I unscrewed the top of the pedal, but then it all became rather easy. The pedal appears to be fully repaired now, and on the commute in this morning I mostly convinced myself that the pedal is designed to fail this way, like a mechanical circuit breaker, in order to avoid permanent damage. Nice design!
The only downside is I bent my 2.5mm (cheap) hex key unscrewing the bolts, which has a red thread lock on them. And I used blue locktite to reassemble since I don't have red. I'll need to keep watch and make sure those screws don't wiggle loose.
