[Fot] Cooked Front Wheel Bearing On GT6

[Scott Janzen]

One of the inner wheel bearings was totally dried out - looked like  
the grease had just been baked black by the heat of the brake rotor,  
transmitted to the hub. The race had turned that brownish gold color  
metal gets after being heated a lot.  The outer bearing was ok, though  
blackened grease had migrated over there, and the bearings on the  
other front hub are fine.  Last event I ran was an enduro, but still,  
only about 50 minutes of driving time.

I had looked at the bearings at the not long ago - smooth and plenty  
of grease.  There's no evidence of actual bearing disintegration, just  
too much heat and burned up grease.
Is it time for air ducts?  I run Hawk HT10s, stock calipers and  
rotors.  Brakes were pulling straight, rotors are not warped -  
possible this side was dragging, but there was no evidence of it while  
driving.  I would have figured the brakes would fade away before this  
happened.
