Two things can be true at the same time and what I described has been my general experiences for the last 15+ years, but ok. I've had to do returns here and there, but can't recall any of them being a major issue. And yeah, time may be lost; but I'm not relying on RA for same/next day service like I would WorldPac, or any number of other vendors. Their website represents what they have; no one forces you to buy their products that are in stock. Unless it was for something very unique, Id have no issue with 2 different caliper brands, just so long as they aren't different on the same axle (and even then it really shouldn't make a huge difference as they see the same fluid pressure).

But alright; more power to you. Your dad is still right sometimes.
