The cam mechanism is probably intended to reduce the amount of boot force needed to lower the toe lever so that adjusting for a specific boot with the assortment of bumpers isn't required, but something is going wrong.
Hopefully the solution is as simple as greasing these small moving parts so they don't freeze together or hang up. I'll take a closer look sometime in the next week.
