In the pic above I now have some free play between pedal and spings assembly. I don't need to push down to remove the spring assembly. I have in the spring assembly in order from bottom:
Red spring
Plastic spacer for red spring
Two rubber spacers
5 washers to remove preload
Preload spring
Plastic spacer
Grey spring
Top chrome T Spacer (not sure what to call it)
I think the issue may lie in the pedal, and that it can now be pulled back further then previously. I have only had the pedals for 2 weeks.
Anyone else encounter this?
