As a person who blew a wheel bearing at the track, they start making a lot of noise and fail shortly thereafter taking the rotor and maybe spindle and axle with them.
If your front wheels ever really making a roaring noise, shut it down and save your rotors, axle, and possibly your spindle. Calipers are probably OK, but pads are likely destroyed as well.
Now Cody really needs that set of yellow pads.
