Brake Pad Sensor (was: Dave, the air lock is open . . .)

     The brake pad sensor issue was discussed here on the list a few months 
     back.  If I remember correctly, there were incidents where the sensor 
     would indicate a worn pad, even though the pad was fine.  Ultimately 
     the list discussion resulted in instructions to disable the sensor (as 
     some listers have done) and rely on checking the brake pad wear 
     I have been having the same problem and have pretty much ignored it (I 
     know the pads are good).  The sensor comes on (sometimes) after 
     driving for a while.  Upon re-starting the engine it's out.
     If your pads are good, the warning light becomes more of an irritant that  
     anything else.  HTH!

  It is indeed the worn brakes indicator.
