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
