if you have a pneumatic jack or some easy way to get one or more of your wheels off the ground, try doing that and manually turning each wheel, and see if you can make that sound come back. this will also help you isolate it to a corner.
yah when im driving it makes that hissing noise, but if i stop or slow down like 5mph it stops. i can also hear my brake pads screech but there not as loud as the hissing noise.
