Just curious about why some people (and a specific kit) say the self adjustment mechanism needs to be disabled when switching to SN95 rear discs. If you do NOT disable it, you are in essence just using an SN95 parking brake handle. And since you are installing SN95 rear calipers, they should mate just fine. So what is the deal, and why do some say this is necessary? (I have installed a self-adjusting parking brake handle on my 1967, in addition to SN95 rear calipers, hence my wonder). Thanks guys.
