On the BX1500 there is a bolt on each side of the pedal pivot that limits how far the pedal can be pushed down. If yours is limited the same, perhaps there is debris blocking full motion or the forward bolt has loosened.

I checked the motion and noticed that the pedal won't go all the way down to the bolt in forward. The bolt is almost all the way up. I couldn't see any obstructions keeping the pedal from going all the way down.
What would keep the pedal from going all the ay down?
