Ok, I changed the front rotors and pads a little bit ago. Took just about an hour and a half start to finish. I only replaced the rotors and pads because the calipers were in great shape and I also only went with the stock size instead of going with a larger braking set up because I am running stock rims and probably will be for a good while. The first picture shows the old rotors which looked to be the originals. The pads were about half worn but not gone by any means. The thing is this, when braking with the older pads and rotors there seemed to be a lack of brake available, kind of like they didn't truly begin to stop the vehicle until half pedal. You could feel the brakes beginning to grab, but it took a lot of pedal to get the job done. I had already flushed the power steering and brake fluid in the truck so I know those were good to go and the back brakes look good as well.
I changed the front brakes and not the back for two reasons; I personally have a limited budget for upgrades every month and I also wanted to see just how big a difference changing just the front would make. So I got the job done and immediately after bleeding the brakes I had better braking overall. Not "Put you thru the windshield" stopping, but a lot more noticable response from the brakes. They are smooth yet firm and now I am going to have to change the rear because if I give the pedal a good push like was needed before the truck does a nose dive. I have to honestly say that for about $140 shipped to my door I couldn't ask for better.
One last note, I have these same brakes on my Dmax and have hauled some stupid large loads with it. This same setup on the Dmax survived a full year of regular driving and a full Christmas tree hauling season without any real noticable wear. Because of this I am pretty sure these rotors and pads are going to last me several years without problems or the need to replace them.
