Replace the sensor wire on the brake pads. When the pads wear the wire
gets cut through and sets off the warning.

You can't because there is no "change break pads" error. OTOH, if what
you are referring to are "*brake* pads", there are two sensors of a
sort, one on the front axle and one on the rear that are really just
small filaments that *break* when the *brake* pads get worn.

Those are BRAKE pads, not break pads.

When the pads are replaced, there is a little sensor on one of the front
brakes and another one on one of the rear brakes. You have to replace these
sensors.

The sensor looks similar to a fuse, and what happens is that when the pads
wear down, the "fuse" is opened by friction against the rotor. While
servicing the brakes, you will notice that there is a wire leading to two
diagonal tires, and two wires leading to the other set of diagonal tires.
The tires with two wires are the ones that have the speed sensor. The one
wire is the Speed Sensor that tells the ABS what to do, the other is the
brake wear sensor.

sorry for the 'break', it was 'brake'
my english is not that good.

i have replaced the sensor, but still get the message on the dashboard.
Is it possible that the sensor is damaged?

Have you replaced all of the brake pads, or just those on the front or rear
axle?

There are two sensors, the other one is on the diagonal tire from the one
you already replaced. As I said in another post, the sensor looks much the
same as a fuse -- it is a very thin band of steel that is fitted over a
small plastic block. When the pads wear down, the block and band of steel
come into contact with the brake rotor, and the band is grounded and this
turns the indicator on. The indicator eventually breaks and must be replaced
to turn the indicator off. If you didn't look at the new sensor very close,
you might have not noticed that it was already broken, in which case the
indicator would remain on. Or, you could have mounted the new sensor in
error, and the metal band is already grounding out, which will leave the
indicator on.

If you only replaced one set of brake pads, the problem is likely that the
other set of pads also needs replacing. This is where I'd be looking first.

On some, the warning light doesn't re-set immediately. Try leaving the
ignition on without starting the engine for a few minutes.
