Detecting brake line wear?

[Robert Deis]

Now that the suspension is completely torn apart, I'm looking over the
brakes and CV joints.

One of the boots has split, but I hadn't noticed any noise or anything
while driving, so maybe the joint isn't damaged yet?  (Hope so..)  I think
I'm just going to replace the boots all around and repack them with
grease.

For future reference, I've got the triple-square tool if someone near
Boulder needs to borrow it...

Also, I noticed some surface cracks in the brake line rubber on all 4
wheels- how worried about that should I be?  Are these things dangerous
now and in need of immediate replacement?

Lastly, is there a trick to disconnecting the e-brake cables on the rear
calipers? Neither caliper will let go of the rotor, but I think it's just
because the cables are hooked...  There are signs of rust in the cable
housings, but I hadn't noticed and degredation in e-brake operation yet.
I suppose I should replace those, too.
