Posted January 22, 200817 yr comment_235051 I have a 1977 280Z, and it (or I rather) have an unusual problem. The red brake light indicator will not go off. But here is the kicker. When the parking brake is fully engaged the light is very red, release the parking brake and the brightness diminishes quite a bit (but it is still on). Any ideas would be appreciated.Thanks,Jim Link to comment https://www.classiczcars.com/forums/topic/26859-brake-light-wont-go-off/ Share on other sites More sharing options...
January 22, 200817 yr comment_235058 Low fluid level in the brake Master Cylinder perhaps? Link to comment https://www.classiczcars.com/forums/topic/26859-brake-light-wont-go-off/#findComment-235058 Share on other sites More sharing options...
January 22, 200817 yr comment_235063 Low fluid sounds right. Possibly, when you apply the parking brake you are augmenting the ground signal that the light is getting making it brighter. Is the same light used for a low fluid warning and a parking brake "on" indicator when the key is in the on position?

January 23, 200817 yr comment_235065 I believe there is a relay under the passenger seat that causes this problem. Link to comment https://www.classiczcars.com/forums/topic/26859-brake-light-wont-go-off/#findComment-235065 Share on other sites More sharing options...
January 23, 200817 yr comment_235088 txz1956 is right, I had the same problem with my 77. I disconnected the relay under the seat and the light went out, but now of course it doesn't come on at all. But It'll do until I can replace it. Link to comment https://www.classiczcars.com/forums/topic/26859-brake-light-wont-go-off/#findComment-235088 Share on other sites More sharing options...

January 23, 200817 yr comment_235093 I had the same problem and it turned out to be the physical contact surface at the brake pedal switch . I just put a rubber cap on the pedal side.Maybe mine was to simple.

I just put a rubber cap on the pedal side.Maybe mine was to simple.That's a different problem. They're talking about the brake warning light on the dash.

That doesn't mean the relay is bad. Check the caps on the master cylinder that monitor the fluid level. They can also go bad.

January 24, 200817 yr Author comment_235254 More info, if I disconnect the relay under the passenger seat the light stays on, and there is wires on the master cylinder, but they are not connected toanything, my mechanic could find nothing that they could connect to, maybethis is the issue? If the wires were connected then that would solve the problem? Does anyone know where they go?Thanks,Jim Link to comment https://www.classiczcars.com/forums/topic/26859-brake-light-wont-go-off/#findComment-235254 Share on other sites More sharing options...
January 24, 200817 yr comment_235256 Try adjusting the switch under the E brake handle, it may not be engaging.Rob Link to comment https://www.classiczcars.com/forums/topic/26859-brake-light-wont-go-off/#findComment-235256 Share on other sites More sharing options...
