[Mgs] brakes

[Peter C]

Paul,
         Agree completely. It seemed that the car was fine until 
driven, not a time factor. Maybe I misunderstood his description, or 
maybe "sponginess" is a little vague.
         I'm just sensitive to this as we spent time bleeding the 
brakes on the race car only to find the closest wheel's bearings had given up.
