Brake roaring/howling noise

I just got a brake job done new brakes and drums on all drives and I’m getting a howling noise like those old school busses. It originally did it when I braked and now it’s making the noise when I’m going between like 30-40. It started making it right before I got the brakes replaced and it stopped for about a week after I got the new brakes and started right back. Do you think my brakes are out of adjustment or is there something else I should be looking for. Nothing looks out of order from my eye.
Thanks guys!!

 

Are the hubs to hot to touch. ?

 

I haven’t touched them. I will try on my run tomorrow

 

Did they check hub bearings for play or pull hubs at all?

 

I’m not sure. I just tried to call my mechanic. Didn’t get in touch. If it was hub bearings would it get louder when I apply brakes?

 

Possibly....stupid question perhaps but did you put tires on this truck recently?

 

Mine was making crazy noise after new breaks and changed again with same problem. Turned out to be brake spider

 

I got 2 tires replaced on the opposite side of the noise a few months back

 

Just check after running 100 miles. All 6 feel the same. Not hot
