Just wondering when others on the board had to replace their brake pads. My 2001 4.4 X5 has 59K miles on it, and this will be the second set of brakes. I replaced all the pads, rotors and sensors in November of 2006 when the car had 36K miles. Is it normal for the breaks to go every 30K? Is there something else that can set this message off?

Thanks
JD
