I have an 83 Z28 with 700R4, My Brake warning light does not come on when I turn the key forward. All the other light do. I changed the bulb and it still does not come on and I checked the old bulb and it is ok. The wierder thing is that when I was bleeding my brakes a couple months ago I remember it coming on because of the proportional pressure switch. Any ideas?

thanks,
phil

 

Does it turn on with the e-brake?

 

No
