Maybe collapsed was not the right word, RUST in the rod assy that
goes from the frame to the axles, there is a shield that the hoses lay in
and rush builds up in and it presses the hose closed. Do you have a manual?
I
could not force air through it with an air hose, but the master cylinder
will push the fluid through it. Been there ,done that.
