95 SL320 scraping noise Left rear wheel

Would anyone knows where this noise is coming from...been hearing this scraping noise in the left rear wheel when driving. The noise goes off and on while the car is running. The noise is much noticeable after being parked overnight or longer. It diminishes a little bit after driving for awhile. Sometimes it goes away as you keep driving the car. It seems like the more you drive the car on a daily basis the noise would be less noticeable or even goes away. I'm thinking of something with the emergency parking brake that causing the noise. Does anyone have experienced this kind of problem? What seem to be the cause of this noise? Please help. Thanks.

Pull off the caliper and rotor I suspect a broken spring. Do you have longer wheel bolts than factory? if long enough they can hit parking brake parts.

Raider,
the back plate was bent and it's making noise when it makes contact with the rotor. Straightened it out and it's okay now.

I had a similar sound/issue, but it was the right-rear wheel speed sensor.
