Squishy brakes after installing my choke.

[CherryK5]

So ive never had a choke on my truck, well i have, but i pulled the blade off and un-plugged it whenever i rebuilt my carb since i really never had a problem with start ups. Well lately its been ****ing cold as all of you know. So i decided i need it back on there

I pulled my whole choke assembly off of the carb and replaced it with a new one because the little cylinder in there was seized up. Well now i have squishy brakes... It isn't that bad, but enough to have me concerned. I could be paranoid.

But then again i changed a few vacuum lines so maybe i had a small leak and now its gone? I dunno..

Depending on the carb, theres a vacuum line right by the choke, or if its a divorced quadrajet, then there is a vacuum line that attaches to the choke pulloff.

Yea i checked that, the cap is a little dry but not leaking. could i route that back to the second vac port on the front of my carb? Or just T it in somewhere?

Squishy?? Ok, I gave up a long time ago saying that one thing could not affect another, after it got shoved in my face too many times that it could.

Normally carb work does not affect brakes per se. It could affect the booster, of course.

Quick test. Engine off, press the brakes and release a few times until they get hard to push.
Take your foot off, wait a second, then press down steadily and hard and hold it. Beyond a certain point, it should be like pressing on a rock. No give, no leakdown.

If so, then release, press down firmly, not as hard as before, and crank the engine. The pedal should go down a small amount farther and hold when the engine starts.

If both of those are that way, and you do not get a hard pedal driving around, then odds are they are fine.

Its possible that you are getting more vacuum than before and they are easier to work now.

Yea they felt fine engine off. Its just that it FEELS like im hitting the floor with the engine on. But i dunno, it may be me over analyzing it. They work fine so i'lll leave it at that.

Thanks for the info.

I maybe have missed something big here, but on my carb the booster is connected to the back, very bottom of the carb. It's below the blades, for manifold vacuum of course. Big threaded connector you use some Teflon tape around. It's also a metal tube going to the connector, so it's fairly obvious.

Between the booster and carb, there is a filter mounted to the throttle cable bracket. There should be nothing else on this line, no splices etc. It's something like 3/8 or 1/4 ID hose, and that goes into the metal line.
