04 double cab break problems

[just1600]

I going crazy here i hope you guys can help me.. I have been having problems with brakes just recently and i belive ih has to do with my new 22" rims but could be wrong considering they weight less than the 20" enkei's i had on when i bought the truck. Well ne wasys the rear drums starting squeling real bad when coming to lights stops,didn't worry to much then started getting worse when stopping all the time...pulled drums off shoes looked fine just quite of bit of brake dust so we cleaned brakes out put them back together fine for a day then started squeling again.. so i tried getting drums turned noise went away i thought i had em fixed about 1500 miles later same deal squeling and starting to make a hopping feel now when brakes were applied...( iknow it's not the front b/c i just put front new rotors on too). So i ordered a set of wagner premium shoes replaced shoes all seemed good for a couple of days then hopping feeling came back i think i need to just start again with a set of new shoes and turn drums again and see what happens what do u guys think??

These drums are very difficult to center on a brake lath, chances are they actually machine the drums out of round. I'm afraid the only fix for this is new drums.
Also consider the fact that your new wheels could need to be centered to the hubs. You may need a special centering ring that fits in the wheel and centers it to the hub. This is called hub concentric. You wheel supplier should be able to get these. If the wheel is not centered it can cause "hopping" during stopping.
I don't really know why your having squealing from the rear. This is very rare, are you sure it is coming from the rear?
It sometime help to drive along a wall and listing to the squeal. You may be surprised to find it is actually coming from the front. A squeal can travel while driving, making it sound like it is coming from a different point.

For more information on Hub Concentric wheels do a search on DJ. He is a Hunter alignment equipment engineer and has done an excellent job explaining this in some of his posts on this subject.

thanks man but i don't believe it's the wheels making the hopping problem only b/c they didn't do it when i 1st installed the rims in january...that and it only hops when brakes are applied..
