Some metal hissing?

[Si23]

So I have no idea what could this be. It drives fine but sometimes it makes a hissing of metal sound. Like a small grinding of some type. I can hear it on the passenger side rear. Does anyone know what this could be?

Might be something stuck between your brake pad and disc/drum????

that'd be my first guess ^

Yeah I'll go check when I get home. It's been raining lately here so maybe some rusting?

 

[webby]

rotors will always rust without use/braking. If you hear it when braking, you probably have rust buildup or something between the pad and the rotor surface. Could be a small stone

So I checked it. Nothing was there. Drove it around and it seemed that it comes and goes. When it does make the sound it gets really loud.

take it to the dealer and have a tech look at it under warranty?

Any aftermarket brake or suspension parts?

 

[Si23]

Nope. Just eibach springs. I was thinking it's my tires since it's balding out. But I'm rotate it to see what happens. My next opinion was the bearing?

I rotated my tires. And well I would say it went away. But I'll drive it after my work to see if it's fine.
