Got a break wear light
But the pads are new 4 months ago, any way to tell which wheel it is short of taking each off and swapping out the sensor ?
|
The wire gets cut by the rotor, has nothing to do with how new your pads are. Sounds like you need new rotors. You can buy rotors with new wires as a package deal.

Um I don't think you're correct there. The nub of the sensor gets worn through when the pads wear down enough to expose it. I mean, yes, the rotor does wear through the sensor, but only when the pad is sufficiently thin to allow this to happen. The sensor is there to monitor brake pad wear, not rotor wear. Your rotors could be paper thin and that alone will not cause the indicator light to go on.
In this case it sounds like it might be just a bad connection. Check the connectors to the sensors to see if one has worked loose or fallen off. Could also be a defective sensor, which you can determine by checking for continuity through the sensor with your multimeter. Also check and see if the section of wire between the sensors has been pinched or broken. http://members.shaw.ca/mtharris/sensor1.jpg Checking for continuity (this one is good): http://members.shaw.ca/mtharris/sensor2.jpg |
You should be able to do all this without any disassembly other than unplugging the sensor connector to do the continuity test.

Sorry, but you're wrong.

Exactly, and it is a lack of continuity through one or more of these circuits that causes the wear indicator to light up.

Ok, lets see what he finds out. I'm putting my money on the rotors.
|
Probably just routed one of the wear indicator wires incorrectly and it got nicked.
|
If you have been doing heavy braking like at the track one may have melted. Probably one of the fronts.

Please. I'm begging you. Think about it. If not, make it $100??;) |

If it's on the Internet it must be true.... lol

Not to attack you but... logically, look at where the sensors are mounted, they are on the brake pads and the wear portion of the pads no less. How is it possible that it can measure the thickness of the rotor? |
And I'd really be laughing my butt off though if we were wrong and you were right Kram.
