"My 2001 C320 brake sensor is still good I guess because by the time I
checked my brake pads the light was not on yet. I only disassembled the
pads because I found out that the metal is too close to the disk that
causes the squeaking sound, so I made a little adjustment, make it even
both sides. By the time I put it back all together the squeaking sound
gone but the indicator went on.I was wondering why the lights come on
the time I fix the brake.Is there any way I can reset it? "
Something doesn't sound right here. In the cars I've worked on, the
metal noise maker and the electrical sensor indicator are independent.
It seems both are telling you the pads are worn out, but you say they
are OK? I've never seen the metal noise generator need adjusting. How
far off could it be and how much pad could be left to be worth fooling
around with compared to just replacing the pads?
