when i was driving today i noticed that i just started gettin loud and obnoxious noises in the right rear of my car....at first i thought it was the brakes but ive noticed that the loud noise only happens every once in a while espeically while making left turns....the sound is kinda like metal rubbing against metal....it sounds really bad and i have no clue what is it.....the sound just started today....

 

Most likely your brake pads are worn down to the wear indicator.

Take the wheel off and check them.

 

I had the same problem after buying the car my drivers side rear wheel made metal to metal sound it turned out the pad was completely gone.

 

im having that right now...dosent sound like metal on metal but has like a weird sounding rubbing noise...i was doing e-brake slides in a open parking lot for fun...i dont know what it is...I too will also benifit from this...
