This is a general response and not to anyone in particular...
I am sorry but in my experience as a car owner and auto field worker selling this stuff( parts and service )OE brakes are some of the worst. I would not in anyway call them the standard you want to compare to if you want to offer the consumer a quality product. More like minimum standards not to kill you or get a car through warranty like most OE parts.
My family and I have had trucks, cars, mini-vans, and suv's from GM, Dodge, Ford's, Mitsubishi, Honda, VW, and even Toyota and the OE brakes on all of them left a lot to be desired. The worst for me personally would be the Toyota( Tacoma )and then a couple Dodge Ram's( 97 and 2001 ). I personally have never seen more than 25K from OE brakes and I drive like an old man.
I have had much better performance and life out of quality aftermarket brake parts. Certainly if you go into the local AutoZone and buy the cheapest value line of brakes they offer you are going to be getting pretty poor quality. They will have marginal performance and life plus tons of dust. That doesn't mean OE brakes are the standard we should look for though.
I can get premium braks such as EBC and Hawk for less than OE and they are leaps and bounds better. The rotors are of a better composition plus they usually come drilled and/or slotted which improves cooling which leads to longer life and improved performance. The brake pads will also have a better composition so they will grab better, last longer, and produce far less brake dust. A no brainer to me. When it comes to brakes( and most OE parts for me )aftermarket is the only way to go with a few exceptions.
OE brake parts are "ok" but hardly "the standard to compare to" IMO. I don't go out and buy the cheapest thing I can find as I know that will be worse. I certainly can go to the aftermarket and buy a product that will outperform OE brakes for less money however.
