Thanks Tortron, I started thinking that too. It makes more sense than my initial impression. Cam, everything is new. I assumed the pads were all the same out of the box. I did leave out the anti squeal things but I don't think that should cause it to fail. Now I have an idea. I have a couple of projects this summer to get done Hopefully that goes well and I'll have the time before winter to do the upgrade to 2nd gen discs I found out about after I had bought new hose calipers and rotors for the 1st gen.
