Can someone help? Need to know how brake pedal ass'y goes together

[MustangLX-5.0]

(92 LX ) A little over a year ago, I pulled the brake booster and master cyl for a replacement. I finally got back to working on the thing. I've got the booster and all back in, but I am unable to remember how everything at the brake pedal goes back together. I remember slightly.. theres a white plastic washer and also a black one. I think there was a clip but I forgot. There are also 2 sensor switches that go back in, but how they were connected and where is kinda beyond my memory. Can someone provide a couple pics.. a diagram or whatnot to help me remember just how everything is fit back together? I would appreciate it. Thanks for any help in the future.

I will look at mine tonight for you and see if I can snap a pic or two. I remember the rod that comes out of the booster goes to the left of the pedal arm. The Brake light switch goes over the end of the booster rod pointing straight off the end. A pin goes through the pedal arm from the right, the nylon washer goes on the pin between the pedal arm and the booster rod (with the brake light switch on it now). Once you have the pin all the way through the booster arm, there is a washer that goes on the end and a clip that goes through the hole in the pin that keeps it all together. As far as another switch, I'll have to look for that. Like I said, I'll try to take some pics tonight.

Thank you for the detailed info. I appreciate it. 4G-KDMP sent me a couple images and diagrams this morning. That was exactly what I was looking for. Your info helps. But just letting you know you don't have to go out and take more pics.

I actually think these images and your info should be within SN's technical sticky thread. That way the info is there for everyone. It's quite confusing especially if you haven't fumbled with the linkage in a couple years.

LOL, thanks for that... it's a good thing you dont need the pics cause I got home and the camera was dead... charging it now, so oh well till the next time.

Anybody have these diagrams? I'm in the middle of my 5 lug conversion and just got the new booster in and cant remember how this switch goes.

Hey, I've still got those images 4G-KDMP sent me in 2009. Just let me find them and I'll post them up.

Cool, thanks!

I've probably got a few more if you need something different.

 

[cardudeusa]

Perfect, thanks. So it looks like the brake light switch just hooks over the brake pedal and nothing else? Like no bracket to hold it in place.

 

[ALMOST STOCK]

^^^ You are correct.

Sweet, I've got it back together now and I'm just left wondering how the heck does the brake light switch work without being mounted somewhere other than the brake pedal lol

 

[MustangLX-5.0]

Ahh hell, those are the pics I have. Come to think of it, I now recall 4G-KDMP telling me he got the pics from Almost_Stock . Thanks.. and at least the pics got posted.

I couldn't find them anyway..

Quick question if someone can answer it. In post #10 , what is that black plastic piece that is within the red circle? I have the very same piece on mine but I don't know what it's for. It looks like it bumps up against a white button in a cable or something.

Is that something to do with cruise control ?

What I circled in red is the Brake Light Switch and it does have something to do with the Cruise Control. When the brakes pedal is depressed and electrical signal is sent to the speed control amplifier and will turn off the system.

If you click on the pic to enlarge it you can see below the red pin that holds the Brake Light Switch to the brake pedal.

Thanks Almost Stock..but NOT that part. see image below. The cable also is not pictured. I just showed what piece i'm referring to and where the cable normally is.

 

[MustangLX-5.0]

lol I guess I shoulda used larger text. Let me know if you can't read it.

 

[ALMOST STOCK]

That is part of the Speed Control (Cruise Control) it's the Speed Control Meter Valve.

I've search most of the day and all I've found out is that most call that specific pieces you're asking about the stop or bracket for the metering valve.

 

[MustangLX-5.0]

Ahh that works man. Thank you for that info. I only asked because when I re-assembled the brake assembly in '09 , I recall having to slide the cable forward a notch inside it's bracket groove because the button was not even touching it when the pedal was released. I figured that plastic piece had to bump against it for some reason but I didn't know what for...

Thanks again ... is appreciated

just rewired the brake pedal switch in my car last night easiest fix is to go to autozone and pick up a brake pressure switch or brake check valve and take your 2 wires from the plug and wire them on to the new switch and you **** will work
