Just wanted to know when its time to do a brake change will something pop up on the screen telling you its time to change them? I am feeling a slight vibration on the brakes when i brake hard assuming that my brakes are almost gone. I just want to make sure so that i wont wait too long thanks

 

if it's vibrations when you brake, the rotors might be warped and need re-surfacing. the pads might still be ok but might as well change them imho.

if you hear squeaking sound when you brake, that's also an indication that the pads are going out

 

There is a warning message that appears on your screen when your pads reach a certain level. However, if you wait till then, you will also have to replace that sensor. Best way is to pull the wheels and check the pads yourself.

 

well i checked them and looks like there is still a little left and was gonna wait till the sensors come on to change them but if i wait till the sensors come one i will have to replace the sensors i minus well change them soon before they come on thanks everyone
