I also wanted to express my appreciation to each of you who increased my knowledge.
 
Thanks to all of you.
 
Is this a great list or what?

Sounds fairly normal, Joe.
 The check valve in the "T" is just that, a check valve. It keep vacuum in the booster reservoir even if the engine dies. That gives you one or two stops. The firmer pedal is because you don't any assist, so it takes more foot pressure to do the job. I believe the line going into the fender ends up in a vacuum reservoir, possibly shaped like a coffee can, and maybe painted flat black. As always, I will acquiesce to more knowledgeable members.

Evenin', and how's everybody?
 
I don't mean to sound ignorant about the following topic, but I just don't understand something that I think y'all can help me with.
 
In tryin' to figure out why the power brake booster isn't working, I disconnected the vacuum line from the booster.  It was connected to the booster by a length of some sort of hose and separated by a "T" which I thought was just a splicing "T."  Well, it turns out this "T" acts as some sort of valve because on the side of the "T" goin' to the engine, there was, inside, a spring and I-don't-know-what-one-calls-it but when the engine vacuum sucks it remains open but it can "close."  Anyway, I broke this "T" so I will be needing a replacement but I don't know what to call it.
 
Here are a couple of things I noticed about this whole situation.  When I plugged the hose going to the engine, the idle (RPM) slowed considerably.  When the hose was freed the RPM for the engine audibly increased.  Also, without the vacuum hose connected to the brake booster, the pedal was much firmer.  Lastly, the other end of this "T" goes off somewhere into the front fender well just ahead of the front left wheel but I can't seem to find out to where it goes.
 
There is no doubt there is good vacuum.   But my ignorance as to how this whole process works with the engine leaves me stumped as to why the brake pedal is different, why the RPM/idle changes by plugging or unplugging the hose from the engine, and what is the purpose of the hose that goes over to the front left fender.
 
Lastly, if I were to replace these hoses (along with the valve do-hicky), what sort of hose would I buy?
 
Anyone have some good advice for me?
 
Thanks,
 
Joe
