So, I am having an issue with my little guy, that I think is brake related.
First off, the brakes on a Namco are about the only aspect of these gems I do not care for.
I started noticing something a long time ago. But, lately it has been getting exponentially worse.
I am about 90% sure this is a brake issue. It is randomly acting like the brake is being applied (while in forward motion).
When this happens. If i simply let it stop, then pump on the pedal a few times it will usually free up (sometimes not).
Or, if I let it stop, then back up a few feet, it will usually free up (sometimes not).
My worst fear is this is actually a hydraulic issue, and not related to the braking system at all. But, it sure feels like the brakes are being applied.
BUT, how the heck would that be happening?! Bye design, this system is backwards. Similar to air-brakes.
The brakes are always applied (by a spring pulling the pedal "up"), and your foot on the pedal (pushing "down") releases them.
I guess I don't understand exactly what is going on inside this master-cylinder? But, I assume it is no different than any other master-cylinder.
A piston in a bore, position controlled by mechanical linkage, controlled by a spring and a bodies foot.
Pressure to the wheel-cylinders in the spring direction. No pressure to the wheel-cylinders in the foot direction.
So, if my foot is on the pedal? How could the brakes possibly be being applied?
To compound my confusion, the master-cylinder is about shot (age I am sure, still less than 1000hrs on machine).
It only takes about 2 seconds for the spring to blow through the entire stroke of travel. I pulled the caps off the master, and it was disgusting inside.
With barely anything left that resemble brake-fluid. I cleaned it out as best I could in place with a sucker, and solvent soaked rags. Then re-filled.
This firmed the apply a little bit. But, the random apply issue (if that is what it is) is still happening, if not worse.
How could I be experiencing an brake-apply condition with my foot firmly planted on the pedal?!
From the diagrams I have been able to find, it appears there is an adjustment at the shoe? It is not obvious at a glance looking at my machine where.
But, my next step is loosen this adjustment, and see if the condition disappears.
Any other Namco owners experience anything like this?
