brake pad worn light just came on. does anyone know how long i have to replace them and of any good pads that are more dust free.

 

Usually not long from my experience. I think the dealer said you have a few hundred miles while he was quoting me an obscene price to replace them. But it sure seemed like it was becoming extremely difficult to stop once that light came on. Eventually, it will start coming on every time you start and move the car until you get them replaced. You'll need to have your rotors checked as well. My '01 2.8Q has 60k on it and they were able to turn the front rotors, but replace the rears, along with new pads all the way around. Total was $515 I think.

 

Just take a look at your brake pads. You can see them thru the wheel. You dont even have to jack up the car. On some cars the light comes on with quite a bit of pad left.

 

Is there a sensors on the brake pads?!
Pls tell me more about it. I am about to change my rotors and pads.

Also, is there any difference between rotors for 15" and 16" wheels.

Thank you.

 

Yes, the brake pads have sensors attached to them so that when you hit a certain level of wear on them, this is sensed by the sensor and sent to the the warning display in your instrument cluster. You also may be able to have your rotors turned as opposed to replacing them. They were able to turn my front rotors, but the rears had to be replaced. I'm not sure about the difference between 15" and 16" rotors.

 

I think you can figure out whether the rotors are different for the different wheels buy doing searches for new rotors online. Some of the sites will ask you what your wheel size is, and you can choose both and compare the part numbers.

My inboard brake pads wore to the point of a nasty grinding sound. Two weeks later the warning light came on... So what's the point of those things again?
