Never could understand why the brake lines aren’t made out of stainless steel tubing. Tremendous hydraulic pressure builds up in these lines to operate the brake system. Doesn’t take much corrosion to compromise their integrity.
Stainless steel tubing is a pain to work with. if you have your car checked over on a regular basis its easier and cheaper to go with coated steel line.
I agree...It would add cost to the trucks but if they wind up having to recall these to replace them it’ll cost them much more in the long run.
And its harder to get a good seal with stainless. I just had this problem doing a fuel line on a ford flat head v8. it was a pain.
Now wait a minute...is the failure due to the INTERIOR of the line, or exterior?
Add to that the fact that regular glycol-based brake fluid is extremely hygroscopic (absorbs water), and as result the lines can rust from the inside out.
Stainless also work hardens due to vibration and then tends to crack. Some alloys are better than others.
