Replaced the rear pads on K7 myself a few months back with some after market ones I bought in mainland China via taobao.com Cost me US$3 for the pair (bought the complete set for the front too at the time for about US$6). What I only realised when I went ahead to swap out the rear pads which were down to the metal, was that the after market rear pad set didn't have the small metal "nipple" on the rear side of the pad. This is essential for use of the parking brake. But not having any choice fitted them anyway, as the work for the purposes of braking, just not for park brake engagement. As it is I have been trying to get OEM or appropriate pads (with the nipple) without any success. Seems to me the pads must also fit other make/models of motorcycle out there, as all online sellers of these pads sell them same ones (without the nipple). Have retained the used pads and will have them refurbished at some point some-place (likely to be NZ on my next trip back).
I also had a hell of a time trying to remove the two locating pins using Allen keys which required the use of closed spanner/bar for leverage.
And may I add FWIW, that this is a shame, as a nipple man myself. YMMV LoL!
