Got the new brakes installed today. Took a few miles to break in the AC Delco pads on the coated Duralast rotors. But once they set, they worked great. I did several mixed speed stops and threw in three or four panic stops to break the pads in and the feel got better and better.
Added the Stoptech braided lines, too. Much firmer pedal and everything feels sturdy and smooth so far.
I used regular flat washers to space the calipers evenly over the rotors. The washers didn't have the exact thickness I wanted to make it 100% even, but I will correct that asap. I'll let everyone know the size.
Overall, this was super simple for me on my 2010 Z71 and I highly recommend the upgrade. Just get the right parts, don't use anything beyond a single washer per bolt for spacing the calipers, and bleed the brakes very very thoroughly. I can't emphasize the last one enough.
All I did for this to work on my specific Tahoe was replace the calipers, pads, brake hoses, four washers total for the calipers, and I went with replica Trail Boss wheels. Research the factory offset of those wheels and spoke clearance to determine what wheels you can use, but I wouldn't get into the business of using wheel spacers. Pet peeve of mine and I think those things are dangerous, but thats just me. Buy the right wheels or don't do this uograde until you can afford to buy the right wheels. Anyhow, good luck and give a shot. It's worth it.
