I wondered about that at first Bones but the Caliper is sliding freely, the Master Cylinder seams to be operating just fine and is returning correctly.
When I got the first set of premier pads, Ivan, the Guy I normally deal with wasn't in at the time so just ordered a set through the other Guy.
When I spoke with Ivan he said he would not have recomended that particular pad for the Rocket, its way to soft.
He is interested in my feedback on the second set of Premier pads.
I think my riding/braking style has a lot to do with it.
As a matter of interest, these rear disc pads are very common, and fit a variety of different bikes, so should anyone every be away from home and desperately need a set of pads, find a local M/C shop they are bound to have a set that will fit.
