Did you reuse the brake wear sensor when you replaced the brakes?
The brake wear sensor doesn't have to be reset, you either have a bad brake wear sensor or maybe the other axle needs brake pads as well
it said something about push the reset to reset the set on dash alert
All you have to do is cycle the key on and off after you replaced the brake pads that were low. If that doesn't take care of it you have a brake pad at a different location that could be worn or you have a bad brake pad sensor
