I can't really be sure if your "roar" is the same as my "roar".
Your's is probably one of two things. If it's sounds like a grinding sound (metal on metal), then it could be your brake pads are worn excessively and grinding against your rotors.
If it sounds like an airplane sitting on the runway ready for take off, then it's your wheel bearing/hub.
