can a brake sensor go bad??? My brake lining light when on, i checked brakes and my rear were getting low. i changed pads and new sensor. is there a way to test sensor? did i put sensor in wrong? i'd appreciate any help as the lining light is bugging me again. or is my front sensors bad, but the linings look good.
