rear brakes squeaking bad!!

[workingdan]

So I got my car running again and my rear brakes are squeaking real bad. I have changed to S10 wheel cyl and bonded brake pads. I am running both large pads. I can hold boost real good but cant stand the squeaking. Did I get them too hot doing burn outs? Should I turn the drums again? Thanks

Brakes are either glazed or some dust is trapped in the drums.
