Every time I put on the gas or brake, it makes a grinding squealing kind of sound that's really difficult to explain. It's kind of like, you're driving on an asphalt highway, but when you press a pedal, the sound made is like the one you'd hear on a concrete highway bridge, driving across it, but much louder. It's not my tires, because they're basically brand new. It's really annoying and a bit worrisome. If I'm not on a pedal, it's fine, but even a hint of pressure, and it's super loud like that. Any ideas?
