Ok so just changed my back brakes about two weeks ago and everytime i brake or turn the back screams idk what is i have checked them and everything seems fine. Idk what it could be any suggestions

 

sounds as though you have 2 problems. If they are squealing, chances are good you got grease on them when you changed them.

As far as squealing when you turn, it sounds as though something is loose or not in it's original position and moves when you corner so it rubs. Need to look carefully at the components both off the ground and sitting on the ground.

 

Was the H-clip put back in correctly??
Did you grease the recommended caliper spots??
Bleed the brake system???

 

Well i did greese it and it just seems to be getting worse idk if this make a huge difference but the rotors that i bought were from autozone and for some reason they were about 3cm on the hub bigger then the old rotors when facing them both on the ground could that be the problem i refuse to drive it now but they fit just fine should i just take the rotors back and try different place ?

 

ummmm..... 3cm is more than 1 inch larger. A one inch thicker hub would render the stock studs useless. Are you sure that's what you mean? Maybe 3mm = about an 1/8th of an inch???

Is it possible the pad wear warning fingers are scraping on the rotors?

 

Yeah sorry it was a little less then a quarter of an inch
