Brake Warning light / emergency brake warning light

[Steve83]

That's how the '92-96 Bronco brake warning works - all 3 triggers are in simple parallel, as this diagram shows:

Can't answer the question B-man, but until you find out you can turn the lamp off by unplugging the connector down at the H-block on the frame rail.
The reason to do this isn't so much for any annoyance factor that the light being on all the time will create, but because eventually you can melt the lens out of the socket.

Seen many of those over the years. Best to do that while you figure out whether to fix it as-is, or create the brake lever warning light.
I like the idea of the parking brake light myself, but could go either way.

Yep, burned out one of those lenses before. Thanks for the info.

I put a spade terminal on the end of the blue wire. If you crawl under the dash and look at the back of you ignition switch, at about the 2 o’clock position you will see a purple wire with a white stripe. I just plugged the spade connector into the connector with the purple wire on the back of the ignition switch.

When the ignition is on, and you press the emergency brake, the new switch provides a ground thru the blue wire back to the ignition switch. That activates the brake light just like the proportioning valve does. They both still work....no wires to splice or cut up....

Blue wire is in the middle of this picture.

Thanks for that info. I will look into this more this weekend.

Bronco brake brackets were designed to have a switch on the front side of the pedal which grounds when the pedal is pushed down. There are two pre-drilled holes in the pedal bracket for it. Its the same switch that fits later model f150 trucks. I got mine at Autozone. Duralast part# SW3898
It just pops right in with one screw. The bottom hole in the pedal bracket is for a pin that is molded into the switch.

So looking at doing this mod...
My E brake pedal looks nothing like yours. Is a '77 different?
Mine looks like this.

Apparently the ‘77 is different. That’s news to me. I found a tweet from Tom’s which refers to it as a heavy duty ‘77 version.

Well...that kinda sucks

Yep, there were (at least) two different models of parking brake pedal assembly.
Changed around '76 in fact.
Not long after that (or maybe even at the same time) they changed the design of the parking brake cable. Then changed it again in '77.

We have pics of the two pedal styles and three cable styles side-by-side, but I don't know where they might be at the moment.

subscribing so i dont lose this info! thanks guys!

 

[4x4man514]

So I ordered the switch but I don't see the predrilled holes in mine neither. Was a 72 pedal different?

 

[DirtDonk]

Could easily have been.
Even though, as far as I know, the overall pedal design from 68 to 75 was identical, it’s not unusual to see variations on a theme. Including holes, no holes, holes in different places, paint, coatings on one, and not another, or paint up to a certain point on one and a different point on others, spring tabs bent different etc.
The big car manufacturers have different vendors and sometimes those different vendors become different vendors or make a slight machine change or whatever.
So yeah, you could have a stock pedal with a hole in it one year and not the next, or one month and not the next. Even though nothing changed except the holes.
So, at least for me anyway, I wouldn’t find a small change like that unusual or unexpected. Especially if it gets in the way of progress! That’s completely normal with these old silly rigs of ours.

I don’t think there’s any way for us to know without looking at each and every year multiple times.

you know i looked at my emergency brake pedal again today and i havent seen another one like it online yet, ???

i thought maybe i got it mixed up with another truck so i dug up the one from my old 72 and dang if it doesnt look just like the one i got. so i know its what came on my new 72. surely i dont have the only ebrake like this?

 

[Steve83]

If you'd post pics of it, we might offer more opinions & insights.

I will. I meant to. I just don't live where my bronco is yet

 

[4x4man514]

Here we go . I wound up getting one of the switches like the original poster had.

Where did you find it? Looked high and low and end up ordering something different.

The one I found was on ebay. I think it was for an old galaxy. The box it was in looked like it was 50 yrs old.

 

[bigmuddy]

Well, hell I was all over ebay. Good find.

 

[4x4man514]

Well, hell I was all over ebay. Good find.

I think I just did a Google search on the part number. There were several popped up.

 

[bigmuddy]

Yea weird, I did the same I think.

You used the part number of the box that was posted in this thread?

 

[4x4man514]

Yes that's the one. The internet is really screwy sometimes. Its usually me that can't ever find An answer online
