New brake pads?? How much time?
 

2001 3.0
The light on my dash just came on 2 days ago indicating that I need new brake pads. I have already replaced the front pads and rotors so I know that it is the rear brakes that need to be done. Once this light comes on, how long do I have until they must be replaced?
Thanks in advance.

ASAP. My light did come on, and I think I got just a few hundred miles before I hit the rotors.

There is no precise answer, since the sensor is on one side only and the other side could be worn either more or less. You probably have a few hundred miles, but if you hear grinding, that's it.

Agreed.

you'll have about 10% left on the pad based on my experience with the x5.

Also, you may have to replace the sensors now too..I'm not sure though.

Rears will be a lot longer than fronts after the light goes on. At least 2k, probably more

I would. They are only $15-17 at the dealer.

sensors will definitely need to be changed. You cannot reuse them once the light came on.

We're talking about a part of your vehicle that your life may depend upon. Take no risks, replace asap IMHO.
