Ok, first, any poll regarding brake wear is utterly meaningless as the biggest single factor is the nut behind the wheel. Myself, I'm a very aggressive driver and I use my brakes hard, so I have to replace frequently. Haven't had the T4R long enough yet, but my Tacoma's OEM brakes went 40K before the front pads needed replacement. I also replaced the rear pads at that time, just to prevent having to frak around with it in January.
A few words on replacement parts & the quality of workmanship.
Avoid the cheap crap. Always.
As far as the pads go, based on my Tacoma, the OEM pads are fine. I was actually surprised that they made it to 40K. I've had the off-brand that you get at parts stores on vehicles in the past, and usually, I don't get 20K out of them. Those Toyota OEM pads on that Taco impressed me right down to my socks. And that's what I'll put on the T4R when the time comes. Probably before the time comes; if I get an extra day off work and my body isn't aching too much to start a project, I'll replace them just so that I know what is on there. (I bought this T4R used)
Second, the rotors. sales claims otherwise, there is a definite difference in the quality of the steel used. The cheap "white box" rotors just won't last as well as the good stuff will. They will warp at lower temperatures, and wear quicker. You could give me a set of white box rotors for my T4R, and I would hand them back to you, and go down to the local dealer and buy the OEMS, or maybe consider slotted premium aftermarkets.
And finally, a few words about quality of workmanship.
When I replaced the front pads on that Tacoma, I also had the rotors & drums turned, general "best practices".
However, I did this on a Sunday, and forgot to consider that none of the better auto shops would be able to turn rotors on a Sunday, so I made the mistake of taking them to the local Pep boys, as they had the advantage of being the only place with a lathe that was open.
Sure enough, these semi-trained monkeys frakked up the rotors. I ended up having to wait till Monday & getting a new set from the local Toyota dealer. Yes, I know. My own damned fault for not planning the job better and taking them to Pep boys to begin with. But I didn't want to have any downtime.
Yes, it can be tempting to use lower cost replacement parts from NAPA/CarQuest or whatever is in your area, but in the long run, it's not worth it.
