Pad makers are getting away from the whole shim thing. Did your new pads come with new shims or were you trying to put the old shims in with the new pads? Either way I'm sure you are fine as is.
They did not come with shims. I was trying to use the old ones. I can't get my mind around what the damn things do anyway.
I drove to town and back and the brakes felt great. No noise.
I am sure the 345's are pretty hard on the brakes.....I will just keep an eye on them at rotation. I have had the truck now for 25,000 miles so I know they fronts at least last that long.
