Hi everyone , I have a 2001 caddy Seville SLS , VIN-Y 4.6 , anyway , I have intermittent "change brake pads" come up on the dash. They are very low (front and back) , but I just cant remember if the sensors need to be changed every time the pads are changed. Any help ????? Thanks , Tim
As stated previously, the sensors are sacrificial. Very likely that they'll need to be replaced if you are getting the message. Recently I replaced the bearing/hub assembly on the front of my 2002 STS. No messages on the dash, and no other indications that the pads needed replacement. The sensors were just being "touched". Obviously, I replaced the pads. Personally, I would always rather replace the pads than the rotor. Ceramic pads were $50 for the fronts.
If your car is approaching 100K, replace the wheel bearing/hub assembly at the same time as these will soon need to be replaced (100K is about the max life). $150 parts for the pair. Otherwise, you'll be duplicating the cost for labor.
Brake pad wear circuit - it's a series circuit, so one sensor wears (you don't know which one) and the message shows.
They are sacrificial - simply a piece of wire embedded in a phenolic puck - when the wire wears through, the circuit opens. If you're a conscientious owner and do regular maintenance checks you don't need the crutch - check pad wear when you rotate your tires. My EBC Redstuff rear pads did not have the sensor cutout so I bundled the (good) sensor wiring and wire-tied it to the suspension arm.
Different types for different years. Call Chris in parts at Rippy Cadillac over there >>>>>>>>>>
