Brake hard lines.........
 

My 72 has been sitting for the last 6-7 years through mostly Texas summers/winters but the last winter up here in PA. Wondering if there is a NEED to replace the brake hard lines. No signs that they ever leaked, and they were fine before I decommissioned it. I will be replacing the hoses and rebuilding all the brakes before putting it back on the road.

Given the description you've provided, and since you had no indications of leaking or significant damage, I don't believe it would be necessary to replace the hard lines. You will be eliminating one of the normal trouble spots, since you plan to replace the hoses in conjunction with rebuilding the brakes. Along with the rebuild, I assume you are planning to flush the entire system and replace the existing brake fluid. This will help remove any remaining contaminants from the system. Good luck! don

i'd wait till you disconnect the flexlines then take a piece of wire and snake it into the hard lins and wiggle it around // then carefully pull it out if it is clean dont worry but if it is coated with gunky cxrap i'd replace the hard lines

Cool, thanks guys!

Re: Brake hard lines.........
 

Agree with what was said above. Definitely flush the system. The condition and appearance of the fluid will be your indication of what is going on.

Anything special to use or just brake fluid?

I just use brake fluid. A cloudy appearance may indicate water contamination which can cause your steel lines to corrode from within. Start by inspecting the fluid in reservoir before flushing. The cap seal often leaks first.
