Itinerant Air-Cooled

When my foot is OFF the brake pedal, goes out as soon as the pedal's pushed down about an inch.....What would be the cause?, this just started.....

One of two things. Either your front or rear brakes have a leak somewhere (not likely since you would KNOW this was the case without having to rely on the light to tell you), and the other, more likely problem is one of the two brake light switches on the master cylinder has failed or come unplugged. Easy fix.

I forgot to say it still stops fine....so it must be option 2.

Hey! I need one of those brake light units, should anyone have one for sale.
(I attempted to change the bulb in mine, and broke the whole dang thing.)

I did the exact same thing!

Ken Madson at www.thebusco.com has 'em.

Ok What if the red brake light only comes on foot off the pedal at night when the lights are on? Driving the bus without the lights on you'd never know the red light has a problem.

If it were wired correctly, the lights would have no effect on the operation of your brake warning light. At lite: brown wire to term. 31
(center, on bulb holder), red wire from brake switches to term. K, black wire (ign. hot) from brake switches to term. 15. This assumes
you have the stock '71 push-to-test warning lite.

This strange then because they do, and this problem started by itself without me going behind the dash.

This could be a goofy gremlin. If you have the push-to-test, it has a side ground to the dash cluster ground so your finger can play "brake switch ground". It is finding its way off of the center terminal of the bulb, because the shell is 12 vt (+) .

Let us know the eventual solution, it is good for the archive.

And such a useful light!
What the heck is the point of that thing anyway? To tell you your brakes don't work? Well thanks.
Don't get me started on tires...

(federal law demanded a brake warning light for those who drive around half conscious every day)

Easy fix. Un-plug it. When you have no brakes, you'll know...

For years, I thought the light was supposed to be beige....
