The Brake Pad Wear Sensor light on the dashboard of my 2000 Catera won't go out. The Front brakes were replaced about 6,000 miles ago, and the rear brakes and rotors were replace about 12 miles ago. I understand that the light first came on sometime after the front brakes were replaced (the car was given to me, and I don't have all the history).
Is there a reset switch, or something like that, or is there some other step that may not have been taken when the brakes were replaced.
The brake sensor is a wire loop which fits into certain brake pads for the Catera. The light goes on when the brakes wear down to a certain level and also wear out the wire, creating an open wire. When the brakes are replaced, the sensors can be replaced, restoring the loop.
You can turn the light off by carefully stripping the brake sensor cables on each of the front brakes and twisting together the two conductors inside to once again form an electrical loop. There are two conductors inside the brake sensor cable. Use twist ties to keep the cable out of the way. My brakes have been that way for years.
My brake light has been on for years too, but I know that it is because I have a loose sensor wire on one of the front pads. Somehow it never occurred to me the just strip the wire and do as Investor74 suggests. Will try that next time I have the wheels off.
Please clarify what you mean by "Tear the sensor end off and screw it to the base". Are you saying that there is another spot to screw in the sensor?
Are these sensors only on the Front brakes? I didn't notice any sensors/wires on the rear calipers when I had them off last.
The trap you are falling into is replying to a post that is almost two years old. Don't know if hgguy is still around or even still has a Catera.
If you want the light to go out, you must complete the circuit. If you can complete the circuit by screwing one of the wires to ground, then do that, but it might be easier to do what I recommended above. Cut wires to the sensor, and strip the wires leading to the sensor and twist them together and tape.
