YES sambam it is a pain in the buns,I found a good write up on how to do it,I would myself just stick with good quality stock(NAPA) or OEM pads or EBC Yellow pads and stock Rotors when I bought my 2007 it had new stock pads and rotors just put on it and they work great because I do not use them much going down big grades as the Allison "Grade Desend" feature works great ,I just put it in manual mode and downshift myself the motor revs to 4+grand and sounds bad but that is what it is designed for,Anyway here is the write-up on it that will help ya to do it yourself....Good luck my man
................ I just did a complete brake job on my dually (rotors and pads) last weekend and I thought I would post a little info about it. Before I did them I had asked on here about how much work it would be and I got little or no info. Basically, a bunch of guys with 2500HD's telling me that it was not a big job.
This is why I posted this in the 3500 forum.
Rest assured, it is a big job. Don't let anyone with a 2500HD tell you it's not.
First, the caliper bolts were very tight, but the caliper bracket bolts were MEGA tight. It took a 1/2" drive breaker bar and a 30" long pipe to break them loose.
On the rears, the axles DO have to be removed. This is not a big deal though, as a 3/4" socket and a breaker bar will break them loose. The axles then slide right out. You will have only a small amount of gear oil that will come out with the axles. Not a big deal.
Once the axles are out, you can access the snap ring and hub nut. The ring pops right out and you should be able to unscrew the nut by hand. If it is a little tight, use the hub socket. (You will need to have the 6 pin hub socket for 3/4 and 1 ton trucks, to re-install the hub and tighten the nut when you are done. So you can use it to remove the nut also, if need be.)
With the nut removed, you can pull the rotor and hub assembly off. It will likely be tight, but a couple smacks with a hammer to the back side of the rotor should break it loose.
Once you have the hub and rotor off you will need to seperate them by removing all the wheel studs. I decided to sacrifice two lugnuts and use them to remove the studs. By screwing a lug onto the stud a little ways, you will be able to hit the lug several times with a good sized hammer and knock each stud out. I ended up using one lug per rotor, as each one took a pretty good beating and I didn't want to bend any studs. Go buy a couple new lugnuts before you start, if you do it this way.
You install the new rotors onto the hubs, by re-installing the studs. If you have a good strong impact wrench, you can probably draw them through with a lugnut. I do not have an impact, so I just pounded them back in with a hammer and an old socket extension. Some people may buy new studs and some may re-use the old ones. I re-used mine. They pounded in just as hard as they came out, so I'm not too concerned about it. The second time I do these though, I will replace them.
Now you will use that 6 pin hub socket to tighten the hub nut. The thread for the axle seal replacement has the torque spec. The calipers and caliper brackets go on as they came off. I replaced the axle flange gaskets and then re-installed the axles. They slide right in, no issues.
The only real trouble I had on the fronts, was getting the rotors off. After the calipers, caliper brackets and the wheel mounting adapter were off (8 nuts no trouble), I could only pull the rotors about a half inch off. There was a thick coating of rust and corrosion on the inside diameter of the rotor, around the flange, so I had to beat both rotors all the way off with a hammer. Once off though, everything went back together without issue.
Bottom line: it's a lot of work. Considering I spent just under $400 in parts, I would think it would cost over $1,000 including parts, to have a shop do it. You'll earn the money you save doing it yourself, though.
I would have liked to have had this info before I did mine, as it would have saved me some running around and extra time. Hope this helps any of you getting ready to do yours for the first time.
Good luck.
