Just want to thank everyone for all the info.
Over the past two days I've worked on the brakes. On Tuesday I took the 3500 to a local mechanic. He let me help him. I didn't say anything, just let him do what ever he wanted, watched, and asked questions.
I bought my Carbomet brake pads from Sam Peterson. I also picked up some Dot 4 brake fluid... unfortunatly, when I went to the mechanic I took the Dot 3 fluid I had also bought. Opps. Will switch to Dot 4 in 15,000 miles. It has a much higher boiling point.
Mechanic adjust the rears first. While truck was up on the lift he adjust through the slots on the back of the hubs. Petty easy. He showed me what to look for.
Then we replace pads. One thing he didn't do was remove the caliper piston, clean it, grease it, and put it reinstall. I asked about this and he said it was a waste of time.
After reading this board, and thanks to everyone who puts up so much good information, I knew it needed to be done. I didn't push the mechanic to do it. That is something I'll do this weekend.
Finally we drained, replaced, and bled the brake fluid. Again, this is something I can do now that I've seen it done.
Yesterday I took the 3500 to Dodge and let them turn the rotors.
I don't have any more shimmy in the wheel when I apply the brakes. However it will pull to the left. If I hit just the emergency brake it stops straight. So the problem is up front. As I said, I'll clean up the calipers this weekend.
Thanks for all the info folks.
