Break pad wear indicator lamp
I recently got a 94 E320 wagon with 92K miles on it. It was given the 90K major maintenance before I got it. A week ago the break pad wear indicator lamp was flickering but has not lit up fully when I put the breaks on. The flickering went away and today has come back. But after I stopped to visit a friend it went away again. The front pads has been changed in Aug 2002. The wire harness has been changed a year ago, so I don't think that might be the problem. Is this something I should worry about?
