ok brake guys, hopefully last time.....

[SwitchBlade327]

OK, finally got everything in, hooked up, and the fluid leaks stopped. heres the setup
60 Pontiac, stock drums.
76 Corvette Booster/Master Cylinder.
wilwood residual valves on both lines as close to the master as i could manage.
Brakes have been bled (not by me this time so they're right)

I have brakes now but not enough pedal pressure, what do i need to do to the home made pedal linkage and pushrod to fix it? It doesn't seem like the pedal is pushing on the push rod like it should when your foots not on the pedal. That also seem to be causing the "hissing" sound when your not touching the pedal since when you just put your foot on in without engaging the brakes it stops hissing. Heres a shitty diagram of how i have it setup...it doesn't look or sound as ghetto as it does here...really....

now as far as the part of the pushrod that stick out through the booster, it's supposed to be adjustable just like the old master cylinder. I'm having a brain fart and can't remember how to adjust it. If anything I need to adjust it out right?

From your diagram it looks like the nut to the left establishes the freeplay on the pushrod. There should be just a little play before the pushrod contacts inside the booster. Probably a 1/16th of an inch or so would be ok. The bolt you are using should really be a threaded rod, i.e. no head on the bolt. Adjust the existing left nut, then use another nut, where the bolt head is now, to lock the adjustment at the pedal.

no one around had threaded rod the right size to be able to thread into the nut of the pushrod, that's why a bolt was used cos it's all i could find. I went to EVERY parts store and hardware store in my area. I was trying adding and subtracting washers to change things kinda the same as having a nut of the backside. this seems like a simple problem, but I'm having a helluva time coming up with a solution. It's one of those things where an explanation in words is kinda hard.....

unless Im seein it wrong-isn't the pedal actually gonna "bend" that bolt deal/when depressed?
should have a rod end or bushing at the joint between pedal and rod?????Im sorry- It just looks wrong to me. http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif

[SwitchBlade327]

there is ajoint where the bolt goes through the pedal, should've mentioned that. There is a pivot point though, the bolt works fine, I'm just not getting the pressure on the pushrod like it should and I can't think of a way to fix it. I just ned the pedal putting a little bit of pressure on the pushrod to stop the hissing. the main concern is getting the pedal firmness where it should be though. I've done everything how I've been told to so far, and the pedal still isn't feelings like it should. it goes down at least two inches before the brakes activate, and still feels a little soft. It's better than before so i know I'm getting somewhere but I'm running out of options and time. I need to try to get this done tomorrow....

damn, thats a good diagram, you got your point across. http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif

[SwitchBlade327]

ok, well since theres no advice I'm just gonna fuckin' wing it and see what happens.....hopefully I don't fuck anything up.....wish me luck.

If the pedal goes down two inches before it does anything then the booster is not working and your brakes are in the same mode as a failed booster on a stock setup. Take off the vacuum line, make sure the booster is vented to the atmosphere by not having the little valve where the vacuum line attaches.
Now try the brakes. Any difference? If not, then the booster is not working!

[SwitchBlade327]

the shit is working, I just can't really explain in text what the problem is.....the pedal gets softer when you turn the car on just as it should. the booster and master are fine though, it's all going to be just a matter of adjustment.....

most cars have a different hole to put the rod on the pedal (1 for maunal and 1 for power). if not you might need to drill one to get a different pedal ratio.

i don't remember seeing a second place for it, the car was power brakes before. Forsakenfew did this same swap and didn't seem to have too much trouble, tried to get in touch with him but he must be out for the weekend or something.
