| Subject: | How does a QS-2 work? |
Today I had a problem with my brakes. I could only make right turns, so I
figured the QS-2 valve. I took it apart and found that one side's plunger
had a small tear in the rubber shroud (for lack of a better description).
So hopefully a rebuild kit exists and I'll order it.
But then I got to thinking since I've never opened one of these up before.
How does the thing work??? Only being able to make right turns means that
my left wheel won't dump air and stays locked.
But looking in the QS-2 I couldn't figure out how a torn rubber plunger
would keep air from leaving the brake. I looked at the exploded view in the
overhaul manual, but to be quite honest, I suck at reading mechanical
drawings. I can't distinguish a moving part from the housing.
Can someone explain to me how this thing works.
Thanks
Ernie

The left wheel could not be locked because if it was, you would always make left
turns. The valve/seals for the left side are leaking.Dennis

Yes, it is very easy, and I've got a request into Doug. My question still
remains however, how does the thing actually work?
