you do need to change your pads, that is the ultimate solution. Also, adjust your rear drums, this will allow some of the work to be transferred to the rear, it will also keep the ass end from popping up every time you hit the brakes. Find a nice clear parking lot or empty street, put the truck in reverse, get up to about 10-15mph, then stand on the brakes. If the fronts lock up, take off a little pressure. Do this about 3 times, then hit drive, get up to about 20 mp, and hit them to see if you can tell a difference.
And yes, you can also put wax on your wheels. I would actually recommend it. As many harsh chemicals people are using to clean their rims, it's stripping all the protective chemicals in the clear coat. I use regular eagle one wet and eagle one clear coat rim polish. It may help you out.
good luck.
