I am having a few issues with my rear disc conversion, i have had it all fitted for a while and its never really worked right.
I want to make sure i have the right cable first before i start looking into other possibilities ( recently had rear calipers overhauled/remanufactured so not them thats the problem)

I cannot seem to get rid of all the slack in the cable, i get it to apoint where i have approx 5 clicks on the handbrake, when applied the threaded cable seems to pull through the adjuster.
It looks from underneath the car like the cable isnt moving through the cresent moon, but when operated it does. Is the cresent supposed to be changed to match the new cable or is the original MK3 item sufficient?

Thanks in advance.
