We reamed out the steel portion of the hoses that were blocked with rust and were able to get all 4 working. I tried to talk him into buying new hoses but he's anal about keeping the original stuff.
Yikes! Give me a call when your friend hits the road with rotted soft and hard brake lines; I want to be somewhere else off the road.
After ten years, soft lines are at their safe limit and need to be replaced even if they look good. If hard lines have rust in them they need to be replaced as brake fluid absorbs and holds moisture even if the car has not been driven causing soft sections to form undetectable from visual inspection.
If it were my car, and family riding it that car, all brake parts and lines would be replaced excepting drums and or rotors. Correct factory fresh master cylinders and soft lines are available to keep car original. One vender is Year One, I won’t post a hot link because their new site sucks at locating parts, have fun finding what they have.
