The sensor on either LHF or RHR has failed / worn through.
New pads come with sensor

						SupporterFriends, last Saturday night the "Brake Pads Worn" warning came on, the orange triangle and the orange brake symbol in the speedo. Brought the car home carefully (about 60km) and haven't driven it since. So today I replaced the front pads which were down but not dangerously thin. On testing, still getting the warnings. So I inspected the right rear pads (where the rear axle sensor is located), only to find they have plenty of meat on them. Still getting the warnings even though there's plenty of pad material everywhere. The sensors appear to be in good condition and correctly installed. Where do I go from here?

TIA, Rob S

						SupporterI've had some aftermarket with sensors, some without. I don't think the Akebono came with sensors.
Correct, no sensors with akebono, they are imho the best choice. Check RockAuto | All The Parts Your Car Will Ever Need for both. Cheap due to high market volume in the USA.

						SubscriberThe front sensor is such a pr&ck to replace (having to remove the inner guard etc), that I have just cut the wires and looped them, so that I don't get the warning anymore.
You have many kms from when the warning triggers, up to >1000km before you risk doing any damage with worn pads. Just check the pads thickness at every service like we always used to before the sensors were invented....

the sensor is not part of the brake pads like some think...
its a separate part as already mentioned, front l/h and rear r/h
and as already mentioned, once its gone off you need to replace it regardless if you think the sensor is good or not. you do pads, you do sensors.
but yes and no, they can come in some brands of pad sets, they are just not part of the pad itself
