[AT] What are failed Master Brake Cylinder Symptoms?

[Mark Greer]

Dean,
No help here but I also have a '68 N600 with a 20' flatbed. It currently has
a 20'x30' building resting on it that I moved with it so I could build my
shop. It has a loose and leaky power steering box that I need to find some
rebuild parts for but I'm waiting for the neighbor to put in a foundation so
I can unload the building and get the truck back home to fix. Mine is a 330
V8 gas with a 4 speed trans and a single speed rear end. It will go about 50
with a good tailwind on a flat road.
