Brake help...

I am looking for a complete brake kit ((rear and front)) disc brakes. My car already has front and rear disc but with the larger tires I would rather have some better stopping power. The problem is I have no idea who offers both systems for the Blazer. I looked into Bear, Wilwood, SSBC, and Brembo but have came up empty. Does anyone know where to get them? Also if there actually happens to be a kit how invovled is changing the four out myself? I am pretty good with cars, most of the work I do myself, but I have never attempted something like this. Thanks for the help in advance.

P.S. I have been complaining about a clicking noise which I assumed was from the suspention. It turns out it is coming from the calipers hence the reason for the upgrade.
