Opinions on brake rotor types
Well it's time to replace my front pads and rotors.
Currently I am using the original rotors and I'm on my 2nd set of pads.
I changed out the rear slave cyinders to the GMC parts and they work great and it's probably why my fronts lasted so long.
I put slotted rotors on my wife's van because she thinks last minute stops is the right way to drive but I notice a little "vibration" on hard braking. Kind of like mudder tires tread vibration but they stop without any fade even in LIE 70 - zero and back again traffic.
So my question to you truck owners,
What are your opinions of solid rotors, slotted rotors and cross drilled and slotted?
I'm not ready to spend the big bucks on new multi piston calipers so its just rotors and pads I'm looking for.

D & S rotors are really nice if you have a need to spend the bucks for 'em. I had them on the wifes' Trans Am and they were awesome, about $435 for the set of 4 but as far as my truck goes, I get incredible life from my rotors and pads 'cause I don't drive like she did... I'll stick with the stock config. cheaper and works just fine. If you're into "overkill", go for it.

I put slotted rotors on my Toyota when I was working in the mountains years ago and they definiltely were an improvement over stock...less fade and seemed to go further between pads...
I have gotten your experience with the fronts...2 sets of pads per rotor and caliper change out, stock. they aren't Ford brakes, but mine are pretty good considering teh payload I usually haul.
I'lll stick stock for now...

drilled rotors will crack. they have no place on a diesel truck. slots may be ok. but solid is best. you need an appropriate pad for the trucks usage. a diesel that tows heavy requires a different pad than a grocery getter/commuter.

That's BS. Where is your proof? They have been used for decades on race cars/trucks that run much hotter than you will ever get then on your truck.

I think you would be hard pressed to find a professional race team still using drilled rotors. as to where my proof is? all over the internet, take a look. call someone knowledgeable and they can tell you. its been known for some time now. drilled rotors these days are mainly a bling factor item sold to those ignorant of the facts because they think they look cool. there are plenty of examples of cracked drilled rotors after a single lap on a track.

^^^ unfortunately, people don't want to hear this
Here's what some web sources:
http://ebcbrakes.com/articles/danger...rilled-rotors/
http://automotivethinker.com/brakes-...d-and-warping/
...or simply google "cross drill cracked rotor"
Another POV:
A rotor's mass is what absorbs heat.
Why would you want to remove mass from a the rotors of a heavy vehicle?
How many heavy trucks do you see with "bling" rotors?

EBC sells "dimpled rotors" and slotted rotors. It's a sales gimmick. They still sell drilled rotors for motorcycles. The picture is from a cheap Chinese knock off and not the correct metal. If you buy Chinese rotors you get what you deserve. There are millions of drilled and slotted rotors out there on street cars and trucks that work great. If what you say was true the DOT would have killed the idea long ago.

Yes, drilling will fail sooner at extreme temperatures in a heavy race car, but you're not going to get your truck rotors that hot. There is more BS on the Internet than truth by far and it's usually quoted in forums like this. If you want get dimpled for the same advantage of cleaning the surface of the pad.
If anyone here has cracked rotors on their diesel Ram from drilling that are not cheap Chinese knock offs please speak up.

I have these on my 2001 Ram Cummins and have zero cracks after multiple trips down the Grapvine carrying 1800lbs of cabover in the back. Notice the fillets? That cures any cracking problems.

By the way, solid rotors crack as well -
