One of the two pistons, the rear one, failed to pop out after I had pushed them back to accept the new pads. I had actually pushed it back farther into the caliper than I really needed to. And I should have cleaned the gunge off of it first anyways. Pushing them too deep also allows the pressure pad to float out of position. The caliper visibly hopped in and out on the slides when lever pressure was applied, this should be a signal that all is not right. Being of limited vision I didn't clue in right away.
And hey this talk about 79 to 1oo degrees is killing me, I rode in to work (about 30 minutes) at about 38 degrees in a fog that left me soaked, and that was only a couple weeks ago. Right now I read about 62, and i am wearing a tee shirt. Nova Scotia is a beautiful spot, but with our flooding this year bring hip waders and put inflatable pontoons on the Valk, and maybe a "return to address if found" label
