How to improve Park Brake Performance with Dr Diff Rear Wheel Disc Conversion?

I run DoctorDiff's 11.7" rear disk kit on my Duster and haven't had any issues with the parking brake holding the car on a hill in either direction, my driveway is fairly steep so it has definitely been parked on a hill.

How many miles are on the rotors and pads at this point? Is the picture of the rotor you posted the current condition or just a picture from when you first installed them?

I tested my car and found the number of "clicks" pretty hard to count accurately, can you take a picture of the lever with the park brake fully applied? Or maybe count the number of ridges visible on the park brake lever when it's fully applied?
Only about 60 miles on the discs!
With it applied as hard as i dare there’s 3 ridges past the upper mount (see photo)- this is 10 clicks in total which may be one or two more clicks than I previously tested it at! I might test it again tomorrow to see if that helps.
