8.75 disc brake conversion kit without parking brake

I think you have to use the parking brake on a regular basis. Applying the parking brake adjust the rear calipers. That is how the Cadillac calipers work that cam in the RamMan kit that I got for my truck 9.25" rear. If you don't use the parking brake on a regular basis the rear brakes will basically stop working. DrDiff kit uses Cobra calipers, not sure if they work the same way as the Cadillac ones or not.

Now if someone made a kit like the Wilwood Kit that has the parking brake inside the rotor hub, then I could just leave out the parking brake stuff. But none of the Wilwood kit will fit in a 14" wheel.
