Ford 420 brakes grabby

My Mastercraft fork lift is a ford 420. The brakes are really grabby when going forward this would be going backwards if it were a tractor when I apply the brakes however easy they grab really hard and push the pedal up toward me in reverse they are good. Any ideas
 
I don't know the reason for them being
grabby but there have been many posts here
about not having the right oil in the rear
end making the disc brakes act up.
Do you know what oil you have?
A good UTF or HyTrans that meets Ford 134D
specs is recommended.

This fork lift. is new to me so I changed all fluids used UTF 134d spec. And like I said the brakes are fine when applying them in reverse when traveling forward no matter how easy I try to apply them they grab and lock up makes a loud noise both brakes are the same
 

SWAG... suspect they are over adjusted due to wear and the housing is worn so that the squeeze mechanism over rotates???? or in other terms, the pinch-ball housing has a groove worn in it. assuming wet brakes... again swag...

Looking at parts diagrams could the anchor point=torque pin for the actuating disc be worn or broken allowing the actuating disc to rotate pulling on the linkage when I apply them causing a hard application and sudden stop again their is no easy braking in one direction forward its fine in reverse
