1987 Nissan Sentra, Lately after starting up my car and driving,
I’ve noticed the brake light on the dash board has been coming on and
off. Sometimes it stays on and sometimes it will suddenly go off. I
haven’t noticed anything unusual about the way its handling, don’t
seem to have a brake sticking. What could be causing this?

The light refers to the parking brake. Try jiggling the parking brake
lever when the light is on.

You may also want to check the brake fluid level.

Does the 87 Nissan have a sensor for brake fluid level?
Really, I don't know (or think so).

My 87 Pulsar does, and it's basically the same car under the hood.

OK, the only time I see the brake indicator light on the dashboard in my
97 Nissan Pickup, is when I didn't fully release the hand brake lever.
There's no other way for me to check if a low fluid level would light
the indicator light unless I dump out some of the fluid.
You have an an 87 Pulsar? So did I. I loved that car. 1.6 liter 4
cylinder, electronic carburetor, 35+ MPG, and could go over 100 MPH.
When I first bought it I thought the speedometer came out of a Z. I did
have it up to 115 mph one early Sunday morning on a freeway when there
was no one around. I had to back off only because I was coming to an on
ramp and was afraid that some one may pull onto the road without
looking, or a cop. :-)

My Pulsar needs a lot of work, but I love the car. One thing about it, the
engine seems bullet-proof. I have corrosion problems and aligment problems
(I need to practically replace everything suspension related), but that
engine just keeps chugging along.
I take it by electronic carburetor, you are talking about throttle body
injection?

I seem to recall an issue on those older Sentras that the way it was
designed... if the alternator had a certain failure... the brake
warning lamp would light. Oops... a minor design flaw. I would of
course check the hand brake and brake fluid level switches first...
followed by a quick check of the alternator output by attaching a
voltmeter to the battery while the engine is running. A reading
between 13.5V-14.5V is normal.

Even newer cars have the system that when the Alt S fuse blows or the
regulator in the alternator fails, both the battery and brake lighst
will come on, though the brake light with be a lil dimmer; the brake
light will glow normally when the handbrake or brake fluid level
switches are activated.
