if your van is subjected to bad weather ,Snow ,sand , salt ,  etc  i
would say change them.

Replace them. Even if the springs on the rear drums are masking the
symptom you observed on the fronts, chances are that the rear lines are
in about the same condition and are close to failing completely.  Brakes
are the LAST system on a car that you should pinch pennies on.

The hoses are exactly the same, the only differences are the length and
maybe the fittings crimped on the ends.

What do you think you should do?

Replace them. Will saving $40 mean anything when one of the rear hoses
(subjected to exactly the same wear/tear as the fronts) blows and you're
shopping for an entire front end for your van ... or worse?

Just replace them.
I bought a 67 Kaiser Jeepster Commando a few years ago that was (and is)
in great shape for a pittance. Really a great deal. Hadn't been moved in
about 11 years, but the guy got it running great about 4 days before I
bought it. In less than the first year I had it, I had to replace almost
every single piece of rubber in the vehicle. Even sitting in a garage
takes a toll on rubber, much less driving it over 100k miles. Steering
bushings (which suck in Jeeps even when they're new), brake lines,
cylinder boots (I just replaced all the wheel cylinders), gas lines, gas
filler tube ($$$), door seals, master cylinder & power booster ...
everything made of rubber was shot from sitting for 11 years. The Jeep
only had 42k on it and had spent it's entire life in Northern California
(very mild weather), far less miles than your Dodge van. You van has
been on the road for than long and has a ton more miles on it with some
very important rubber parts failing right now.

Yank & replace _all_ the brake hoses and you've bought some of the
cheapest peace of mind you can get with your Caravan. Also at 130k, you
should be saving up for a timing set for it, or at least thinking about it.
