Brake Booster riddle - can you solve it?

Faith
The only thing i can see that needs attention (baring in mind i can only go on the information and photos shown here) is that 18" of rigid brake line seems to floating in the air without any type of fixing. It then goes into a union which again seems to be floating about. Not exactly 'scary!', but could use some attention.
It's good practise to fix the rigid brakes lines to the chassis every 8-10" if possible. Your rear lines could possibly fracture (with vibration) at the point where the two join. I can see why this was done, if you said you had a broken line into the master cylinder then, it looks as if only the front section was replaced.
With regards to improving the efficiency of your system...(there has been plenty of advice so far).
But before you go and change things and spend money unnecessarily, I would start by getting the linings adjusted up so the entire length of the shoes make contact with the drums. Do a few miles and get them 'bedded in' and re-evaluate.
The pedal ratio can altered fairly easily, get someone to weld up the orginal pivot hole and redrill accordingly, or you can probably use a smaller bore master cylinder once you know which one you have. I would consider examining the rest of the brake lines and get them replaced if workmanship looks 'dodgy'. You may have to anyway if it turns out they are connected back to front.
BTW i'm learning things from this thread also:D
Cool cars are even cooler when you know everything is well engineered enough so you know it will never let you down.:cool:

OK, I'll check how many brakets are holding my rigid brake lines to the frame.
Also, there were never any leaks, that I know of, in the lines. The master cylinder was VERY old and leaking out the top, so we replaced it with brand new one. Here are some photos taken from my "repair log" webpage:

My buick finned drums (front) What year are those? Can you guys tell? Eric put those on but he did not seem to remember exact circa (year) of the drums.

Can anyone tell me what those are? (back wheels) - Are they also Buick? I think Eric put Chevy wheels in the back becauxe I have a Chevy S10 rear end and he said bolt pattern did not match... Which makes me then wonder what these drums are... Whatever they are, they will need some TLC soon (sand blast & powder coat?)

If you guys see anything worth mentioning in these photos, fire away :)

Now on another tangent a few things you guys need to know about me (nothing to do with cars, but entertaining nonetheless LOL).

1- I don't think I am a genious by any means. I did not mean to mention IQ to show off in anyway. It did not even cross my mind that 163 was a reason to "show off". I don't think it is that high of a score. Now I know 163 is a pretty nice number but I am reminded time and time again that compared to the amazingly intelligent people out there (inventors, researchers, engineers) I am real dumb :rolleyes:. Oh, and ignorant, too.

2- However, there is oftentime a tendancy for people to conclude that a woman who is kinda pretty is usually also kinda "dumb", so a 163 IQ is a good way to prove the contrary:D . Not that anyone here has ever implied anything like that, I am talking about the general public, people out there, not you guys. You guys have actually been very supportive despite the fact I am a woman who is still VERY ignorant when it comes to hotrods (but learning Faaast).

3- About looks, notice I said above "kinda pretty". I usually shrugg my shoulders when people say: "you are beautiful" (yeah, right, sure!). Because I do not see myself that way. Angelia Jollie is beautiful, me, I am cute at best (on a good day LOL). Of course I look cuter when I am driving my roadter ;) . But I have a mirror you see, and sometimes in the morning when I look at it I go: :eek: (HOLY SMOKES - I just gave myself a heart attack LOL). I grew up an ugly ducklin, skinny as a rail and I was a complete tom boy. I was by no mean the popular, pretty girl, cheerleader kind growing up. More like the nerdy, brainy loner, really. I think I never even wore a dress until I turned 18. No kidding. Fortunately, as years went by, the little catterpillar turned into a nice little butterfly and as more years went by, the butterfly did not lose too much of its pretty color, like some other butterflies its age have. In short, I am aging gracefully, like my roadster hehe...

So to conclude, I do not think I am either a genious nor a beauty, just a woman who, on a good day, can turn a few heads and still carry an intelligent conversation.

So there, now you know about my nerdy past hehe.

Yes Sir :) we sure did replace the stop switch. Good job spotting it from a photo!

rear of master leaking... YOu are referring to the old MC I assume, right? That thing was leaking from every orifice :LOL: - I am exagerating but that was the first thing I did on the car - GET RID OF IT!

Is this a Mopar master cylinder? (It's not the popular Corvette style master cylinder.) If it is plumbed backwards, it will make a big difference! There's a "balance spring" inside the master cylinder that's designed to compensate for the different amounts of brake fluid that's required to operate the front and the rear brake circuits. By the small amount of wear that's visible on your front brake shoes, I'd say that your front brakes aren't doing much. How many miles do you have on these front brake shoes?

FYI . . . if you'll look inside the reservoirs of your master cylinder, you should be able to see that one of the reservoirs is larger than the other. This larger reservoir is for the front brakes, which are frequently disc brakes, which draw more fluid from the reservoir as they wear, hence the larger reservoir.

I had to give a tow to a guy in a Model A that had Buick brakes. I was concerned that he might run into the back of my truck, so I asked him to step on his brakes whenever I raised my hand. He about put me through the windshield of my truck the first time he stepped on his brakes!!!!

:3dSMILE:

Rear brakes look like the stock GM drums that came with the S10 rear to me.
