When I push the parking brake, passenger side locks up but not driver's side

So when I push the parking brake, passenger side locks up but not driver. I tested with rear axle on stands, front wheels blocked.

Heres a video to what im seeing in the driver side

When I move the bell crank full articulation, i barely get any movement at all... its like, so little. I cant see this as enough to hold a wheel for sure.

Can anyone think of what could be going on?

 

Also as you can see, brake pads are all even except for front lower section, it's super thin there...

They both move just fine and are not seized, I can physically see them and move them easily myself

 

It doesnt take much movement. I adjusted mine so they both locked up on the same click if the e-brake pedal, but i have lsd...open diff might be trickier.

 

Front and rear lower section is the parking brake section. Parking brake may have gotten left on when driving? Need to replace if unable to adjust them anymore.

 

Well there's this...

Interesting, yea something must have happened for the lower front to be so thin. Looks like new pads are in order
