m1008 brakes sprung a leak

[Sam27]

This is not really CUCV specific, more like basic maintenance, but... I sprung a leak at the driver's rear wheel cylinder at some point recently. I noticed it when the reservoir went empty. It appears to be leaking right at where the steel line goes into the wheel cylinder. Any thoughts on the source of the problem? My first instinct is to just replace the wheel cylinder, but I don't want to waste money and effort if the problem is really just that the hard line itself is rusted. Any advice?

By the way, is the wheel cylinder the same part as for a civilian K30 from the same year (1986)? I've noticed some stuff on CUCV's comes from older model years.

1984 K30 with the J code 6.2 will get you civilian parts. New wheel cylinders are cheap, get one and if the line looks bad, replace it as well. You might spend $20 total. Pretty cheap for not having to worry about it or mess with it for a number of years. Make sure you adjust your shoes when done with the hydraulics.

Judging by the looks of that line, I'll bet the line has sprung a leek.
Bend and flare a new line, and look at the rest of the lines, cause they probley are not far behind from popin a leak too.

Thanks for the help. I didn't see the replies because something is up with my E-mail notification... I replaced the cylinder plus the line up to the splitter. Everything was so rusty I had to pull the whole backing plate off and grind the bolts off to remove the old cylinder. I'm grateful I was able to separate the brake line from the splitter.

it might be a good time replace the rest of the steel lines as money permits if one is that rusty the rest will follow . As you replace lines it puts pressure on the old lines weakest spots . So at minimum you want a complete inspection of the lines especially the ones inside the frame rails .It also may be easier with less broken parts now.
