disc brakes

Uhm, unless you have a specific question, that's not really a do-it-yourself project because there are a real lot of things you can do to introduce problems and there's a lot of things professionals do to avoid problems and liability issues. If you still want to try it, I can post a whole bunch of things to look out for, but the best place to get the procedure for your truck is the factory service manual. That manual is a real good investment anyhow if you plan on keeping the truck and want to do other work on it.

I don't mean to discourage you, but if you have to ask how to do brakes, I have to ask if you are interested in learning how to work on cars and trucks or if you are just interested in saving a few dollars? If you want to learn how to do your own repairs or want to become a mechanic, I can give you all kinds of help. If you only want to save the cost of paying a professional this one time, you will be money ahead to let them do it once you consider the cost of tools, aggravation of working on the ground, time, and the many things that can go wrong.
