Has anyone found a fix for heavy vibration during braking, or the cause.

I cannot find a corrolation between speed / load / temp, seems to occur most of the time, but not sure why not all of the time.

Has anyone found a fix with specific brake pads?

 

Your rotors are warped, you need to get them cut/replaced. A search will give you endless threads about it.

 

Any idea on why this happens, read a lot on another forum on people with the Acura Cl having this problem, and they couldn't figure out why.

 

Most of us beleive that the brakes are undersized for a car of this size/weight... Acura should have put larger brakes on it from the factory
