Surface Rust on Brake Hose

It's no big deal. And it's the steel hardline you are refering to, not hoses I assume.

If it really bothers you get some rust stop paint and just paint the lines don't even bother sanding them, you can only make trouble for yourself by doing that, just paint. Even kyron will do a decent job in slowing/stoping the rust, especially if it's a real light bit of it the way your description sounds. Anyway by the sound of it there is no reason to be concerned.

I put marine grease on all my brake and fuel lines. They are 21 years old without failure here in the rust belt. I might favor the paint though if I were starting over, but grease is fast. Also, Lubri-Matic makes a product called Corrosion Pro that sprays on and holds very well. You can spray those sections that go above the frame (if you have one).

Yep, that works well too.

Thank you all for the answers. You guys are wonderful.
