I'm really frustrated with my brake..
I had noise come up from the rear brake, only when i hit the brake like halfway down. If i push the brake deeper, the noise gone. I just replaced brake pads last year,and i don't drive much, less than 10k miles per year. So i think the rear rotor need to be replaced. Then i bought new rotors, and apparently the brake pads wears is not even, may be because the rotor is bad. So i changed both rotors and pads, all brand new. Now, the noise is still there. Anyone know what wrong with it? Rear caliper problem may be? It's not squeaking, but more like some metal touching/dragging on rotors, may be. Any kind of help would be really appreciated.

Cheers,
