The line rusted from a plastic loom that retained road salt resulting in a pinhole in the line. It rusted from the outside in, not from the inside out. I've owned the truck since February of this year and use it for storage on my property. It's not street driven, but still requires brakes to be driven in it's limited capacity as a mobile storage unit.

I'm not concerned about possibly breaking a bleed screw off to exchange brake fluid on a truck that reaches maybe 5 MPH in my backyard,, but thanks for pointing out the obvious.

FWIW, I've never followed the 3 year brake fluid exchange in my own vehicles, and the lowest mileage vehicle I own is a 1999 GP with 111,000 miles on it. Most of my street driven vehicles range from 200- 300,000 miles on them, I probably know a little bit about vehicle longevity and upkeep after taking care of customer vehicles, as well as my own fleet for over 50 years.

I also run my oil for 30-40,000 miles, also not typical in conventional maintenance schedules, but if you properly filter motor oil, you don't have to keep dumping it to keep the oil, and engine clean inside.

I'm not disputing that brake fluid with a DOT 3 is hygroscopic, it is without a doubt, but letting a vehicle sit without regularly being driven is much more denigrating to a brake system, such as hobby cars commonly on this forum.

The water, and sludge definitely settle in the lowest portions of the brake system causing corrosion and deterioration of all components in the system. Exchanging brake fluid taken from the highest point of a caliper (the bleed screw) isn't going to remove anything from the bottom of the caliper cylinder, is it?

All that being said, I'm not concerned about draining, and refilling the brake fluid in this vehicle.
