68K!  Where have you been storing this 13 year old car?

The rubber outside cover only offers abrasion protection for the braided
reinforcing cord covering the inner fluid conduit.  As such, age cracking of
this outer cover is a non issue, IMO.  If you do replace the rubber lines
and know nothing of the caliper and fluid service history, I would also plan
to overhaul the hydraulic interiors of the calipers at the same time and
flush.
