Brake Pad Sensor
At what point does the wear indicator trip? My car currently says I have 2500 miles until the rear pads need replacing, but shows the fronts are still at 30,000. I know one front pad indicator was replaced under warranty because it shorted out.
At what point can't they be reset in the car? I'm shopping around for pads and rotors now, but wanted to ask the community what the deal is with the sensors. |

I think that the sensor have two stages of detection. Once the final stage is triggered , you will have a red dash light and you will not able to reset it until replacement of the sensor. Usually the rear pads will get worn way before the front because of the DSC. I just changed the pads, rotors and sensors front and rear at 65 000 km

That makes sense about thhe DSC. My mileage indicator on the car shows I have about 2500 miles until I need a rear brake service. I've got to take the rear wheels off and actually check the pads, maybe the monitor is wrong. But at what mileage do the first stage trip? |

The mileage that your car tells you is simply an estimate (a timer) based on when it was last reset. The physical sensor triggers when the pad has worn down enough for the sensor to contact the rotor and break the circuit.

Yes, I was able to do it for a couple of weeks before getting the new sensor and replace the rotors and brake pads. I think the sensor are the same even for F series as realoem shows with the parts number

Up until a little bit ago, I thought the mileage reminder was tied to the sensor, but it's not the case. I'll definitely be taking a wheel off and checking the pads before I buy replacement parts. Seems a lot of people have taken them off to find out the service reminder was wrong. |
