Gl brakes

[asman0161]

Hi guys
Wonder if anyone can help me, i have an Gl320cdi 57plate which i replaced the front and rear pads and sensors on and still the 'brake wear' light is still on.
I have replaced pads on my other mercedes before and the wear light goes off straight after i replaced the pads and sensors.
any ideas?
thanks.

Try leaving the key on with all the doors shut for 30mins
