I’m 100% with you. Bought the Wagner pads for the discount/rebate and they were junk. Replaced with the gold/platinum Carquest house pads at AA (made in India) and they are GREAT pads. Low dust, good performance, long lasting and quiet.I've had much better luck with the AutoZone Duralast Gold/Duralast Max brake pads on our old 1999 Silverado and 2004 TrailBlazer than I did with Wagner ThermoQuiet pads. The ThermoQuiet pads wore out prematurely (under 30,000 miles) on both vehicles.
I can't say anything about rotors as I have not replaced any in many many years.
All my cars now get the gold or platinum house brand pads. I really like them.
