On the rear axle near the left hub is a brake line T that has a metal brake line going to each wheel. But also going into that T is a rubber hose that ends about 2' away above the left rear tire. What is that rubber hose?

That rubber hose is worn and needs replacing. Getting another hose will be easier if I knew what it was and what it did. I looked thru the service manual but it doesn't talk about plumbing much.

Thx guys

 

It's just a rubber brake line hose, and if you're going to replace it do yourself a favor and get the steel braided brake line instead of the rubber. It's flexible like your rubber hose, but it doesn't expand like rubber, so your brake peddle will be firmer.

 

But the hose ends near the top of the left rear wheel. Since when do brake lines not go somewhere?

 

snap a pic and post.

 

I believe that is nothing more than the rear axle vent tube. It shares the brake line block mounting bolt, but is not part of the brake system.

 

Ah, that could be it. I did take some pics but seem to have misplaced the cable necessary to get the pics out of the camera.

The rubber hose doesn't just share a mounting bolt, it shares the actual brake hydraulic fitting that is fastened to the rear axle. But the fitting's guts are a mystery so it's entirely possible that the hose does not connect to brake fluid, but instead passes thru the fitting into the axle.

It's a pretty flimsy looking rubber hose and doesn't look like it was made to withstand 500psi brake pressure. Not to mention it doesn't go anywhere <g>.

Thx Miami Son

 

Sure sounds like the vent tube to me.
