I second that, you WILL tear up pads if you get into sand, or such. If you really feel that the cost to beneft ratio is no object, then spend the money on sloted only rotors, 100 series ceramic pads and s. steel lines.
I'll respectfully disagree, and this is real world not speculation, but i've had all four of my wheels BURIED in sand, gritty gravely mud, small granite stones, and most recently a mix of all the above. It was so severe recently that the mud totally plugged all the holes in all the rotors.
When I looked at the pads they were fine. When I looked at the rotors they were fine. So, I'm just saying that so far I have stupidly pushed the limits of the rotors in terms of spinning them through this crap over and over and over and never have had a problem. I hope I never do yet for a worry wart like myself, I just do not worry with this anymore.
BTW, even with the rotors and pads hand cleaned but the holes still evenly plugged with mud (on purpose) there was definitely deminished braking ... sort of a floating effect found on the pedal almost like the holes allow the air between the rotor and pad to travel through the rotor as opposed to pushing back on the pad. Not enough to worry with but impressive that the pads bite so fast when those holes are clear and that they hesitate or levitate just momentarily when the holes are plugged even. Hard to describe, and yes it is indeed entirely possible that what i'm feeling is simply trace amounts of mud that the pads pull from the holes but again this was after a hundred miles of driving with the pads scraping off all excess mud, two or three washings with hose to get the mud around the calipers off, removing the wheels and washing with water, removing the pads and cleaning the faces, etc. So, i'm pretty sure the mud that is clogging the holes is dimpled in or perfectly surfaced with the face of the rotor and therefore no longer laying itself over the rotor.
Anyways, who knows, after saying all that, just for more peace of mind, i think next time around i'll just get the slotted-only DBA's and the high performance PBR's (100 series up front, 80 in back), HTH.
