Early Cruiser Brake booster bracket.

[WheelingPiazza]

I have a 63 fj 40.. I am currently in the mist of installing a mini truck booster and master inplace of my current stock setup and have a few quesitons. I have searched and read the tech articals and it really doesnt give me a good answer.

I have a booster bracket simular to JT;s and a few others I have seen on this board. I dont like how far it spaces the booster off the firewall to clear the FW brace and I dont like the idea of lengthing the pushrod more then a 1inch or so. I have no problems cutting this brace and modifing the bracket. My main questions are this.

1. Does any one have the measurements from the firewall to the booster on a brace cut installed bracket?
2. How does one lenthen the pushrod, Simply getting a threaded cupler and getting some all thread?
3. If I space the bracket out right do I have to worry about the clutch master clearing hte firewall?

Any information is useful, any catchas or anything would be helpfull.

You have no problem cutting the firewall brace, but have a problem lengthening the actuation rod? What is your issue with it spaced off the firewall? There are A LOT of trucks running around with this adapter set up, that work fine. Wardens made an adapter for years for this specific issue.


You answered your own question with the all thread; re read it. Get the parts from a decent hard wear store, OR, cut the original one, and WELD it back together, or have someone do it for you.

If the adapter were spaced out correctly, there would not be any interference with the clutch master cylinder.


Install the bracket like it was designed to mount, and run it.


Good luck!

I have the Wardens adapter, I have no issues at all. Only possible problem is if I were to run a Aisin 2 barel carb instead of the 1 barel.

I sould have been more clear. I am running a TBI 350 so thats not a problem.

1. I dont like the look of having the booster extended that far off the fire wall.
2. I think its to much leverage on the firewall.

3. My current measurement off the brake actuator rod is 5 and 1/4. With the bracket this drops the distance down to 2 1/4. That means I ahve to add 3 inchs to the rod which I think is to much.

So by cutting the brace, and cutting down the bracket 1 1/2 inches that basiclly means I can lengthen the rod by 1.5 inches which I can remake the end that attaches to the brake pedal assembly to accomidate this. I think thats more viable solution.

So with all that being resaid.

1. Does anyone have a measurement off there bracket with out the fw brace?
2. If I space it out like I want to will I have other issues like clutch master interference or ebrake cable interference.

Too much leverage on the firewall....


and you want to cut into the integrity of it...


Well,

Looking at the picture that John posted up, you can see that if you move the booster towards the bulkhead, it is going to interfere with the clutch master. Now, you have the booster that you are going to use on hand? If so, measure from the center of the booster, to the outside edge, and then visualize the same thing with the brake master removed, and you should be able to deduce if there are going to be fitment issues. If it were going to be close, I would not even mess with it. The mini truck boosters are very close in outside diameter to the drum brake booster that John has pictured on his truck, but seem to be a little thicker from front to back, so that my place your clamp ring area of the booster, which is going to be the largest part of the outside diameter, conveniently right in the way.

Oh, and perhaps the voices in your head are not audible to anyone else reading what you type out here...


Good luck!

Thanks steve, I will measure it toinight.

I am using a mini truck booster and master. The one piece I am missing is a updated clutch master cylinider.

2. I don't understand why you think it would be "to much leverage on the firewall". The stock manual master takes a lot more pedal pressure to operate the brakes than the power booster setup does. Isn't that the whole reason to go to power brakes?????
I mean there is so much more force being put on the firewall with the stock master than it will receive with the booster, that logic makes no sense.

1. Now if you don't like the look of them thats a different issue.

I have seen many Cruisers with Danny Warden's adapter and it has worked great. I would go that route if I was in the situation you are in my .02.

Also, I do beleive Danny still has some of these left. he did as of a couple week ago when I wheeled with him last
