Stock master cylinder

[militarypotts]

For anyone who has the stock master cylinder still in their truck, maybe you can answer my question. I was wondering about the rubber hose leading out the top of it. Is it just a breather, or should it be attached to something? I still have a hard time understanding how a truck of this size and weight could have such a tiny master cylinder.

It's just a vent!

Yes, that hose is just a vent for te master cylinder as Lee has already said. It goes to one of the pipes sticking out of the air cleaner. Part of the attempt to keep water out of it. If you have the fording kit that hose would keep the brake fluid dry by essentially moving the opening to the master cylinder up high.

Ok, got it. Good to know. I figured a breather, but I just noticed mine wasn't connected anywhere. I'll have to climb up and check it out. Thanks guys.

By the way Don, I don't have a fording kit, but I sure like the way they look up front. Extending the tail pipe straight up is another story. I know you don't have to use both front and back. Those kits are rather hard to come by also. When you do, they can be very pricey. I barely clear the garage door opening now, maybe by an inch. Not sure if the breather tube and cap rise above the highest bow in the roof or not. Maybe a winter project, we'll see.

Yep attaches to the port on the back side of the air cleaner inlet pipe. You can see it in this pic sticking up and looping to the inlet pipe in the back. Opposite the one on the front side.

Thanks Dave. I need to go check this out. I thought it was connected at one time, but now the rubber hose is just tucked behind the air cleaner inlet.
