whenever i start my car, i would hear this hissing or grinding sound on my passenger side. i would hear it, then it would go away. i dont think its my intake becaues it stops when im not in motion. has anyone else experienced this?

 

ttt...im guessing my brake pads/rotors?

 

if it is right when you start it up and momentary, my guess would be the ABS doing its thing.

 

but it was never like this. it recently started. should i have it checked?
