I have two hoses connecting to the rear brake line junction box. One of the hoses is split in half, but the back brakes are still working. What is this hose? Is it anything i need, because evidently the other hose is supplying the fluid.

 

A hose? or the sleeve for the parking brake cable?

 

Does that connect to the brake line junction box too? It looks like a hose.

 

maybe your car is different than mine. There two hoses, one for each (d/p) side. Not sure if that is what you mean.

Here is a 1966 diagram

 

The hose comes out of the top of the junction box. It's not a high pressure hose, it's clamped on there. It goes into the body, through a grommet and stops there, because i pulled it out of the hole. It doesn't look broke so i believe it ends right there. Evidently it's not that important but i still would like to know what it is. Thanks

 

So, let me get this straight. You have the hose coming from the master cylinder (pressure differential valve) into the junction, two hard lines from the junction to each side, plus another hose?

DSM had a possible answer in your other post

 

Im sorry, i was vague, The junction box on the rear axle. It has two rubber hoses coming off it. The hose im talking about clamps on a nipple on the top of it. OH, Could it be the axle breather? THATS probably what it is. Because the hose just ends at a certain point. Thanks for all your help

 

Thank DSM, he's the smart one here

 

Axle breather? *Soaing goes away scratchin his head*

 

What he said.

The rear distribution block bolts to the rear axle with a hollow bolt. Axle vent clamps on top of the nipple on that bolt
