invsibrake question
I have an invsibrake system installed on my coach. I have had it for about a year and a half. It has worked properly until recently. Everything seems to be working correctly except the light on the dash does not always light up when I apply the coach brakes. I have checked and the brakes on the tow vehicle move when the coach brakes are applied and I can here the compressor running on the invisibrake controller under the seat. One thing I can do is push my tow vehicle brake another two - three inches by hand. So my thought is maybe the brake cable needs tightening a little. Has anyone had a similar problem?
