wearing out sound on back left wheel!!

hey just need some info my left rear wheel is like making a squeel/scraping sound for some reason and its not my break pads cause there fairly new and my rotors not warped either so im kinda stumped so yeh any help would be good thanks!

 

how about the hand brake shoes?

 

under what conditions does it make the noise?? accelerating/braking? etc

 

Pebble or something between the stone guard and rotor?

 

theres alot of moving parts down there... it could be anything really

 

possibly wheel bearing

 

when i brake it does it lightly and then take my foot off the brake pedal it gets louder after that lol

 

nah man checked everything dunno wtf it is could it be the shims or soemthing ?

 

Did you actually take the wheel apart and inspect the bearing? thats the only way to be sure.
