I have a 1998 Integra LS 2dr. When I drove it into town this morning, the emergency brake light was on. I pulled into a parking lot and tried to release it further, but it was all the way down. I continued on my trip, and the light came on again, and then it went off. It did the same thing on the way home. I don't smell anything, so I don't think the emergency brake is actually engaged, but it just bothers me that its on. Any ideas about what the cause might be?

Thanks
