So far so good, you've done the recommended break-in period. I have used these pads on all 4 corners of a 16 Silverado and had about 500 miles on them. I feel they stop better than the standard blocks I removed, falling off about 30% in the back and 50% in the front (I think the fronts should have been replaced on certified testing). They hold up well, feedback is as expected and no noise has been heard so far. The original discs still work as they stayed within specification. Hopefully we'll see how they fare over the long term.
