Ok, let me clarify. The light never came ON before changing the pad... Even with the brake pad touching the rotors it never came ON. After changing the pads, it did. He even showed me the sensor and the black padded thing around where the wiring thing was open but the wire was NOT cut, i repeat not cut. The pads in question are the REAR pads. I really careless about this sensors since i always check my brake pads every know and then. I just want the lights off without having to replaces these sensors.
Hope that helps.
