The left front brake hose corroded (metal part) and broke near the the crimp fitting. Corrosion was not visible due to rubber sheave covering the crimp fitting connecting the hose to the metal line part.
During inspection for vacation found rust and corrosion where brake lines are threaded into brake assemble on front wheels. There is a rubber bumper to protect against rubbing but if pushed up to far onto crimped fitting it allows water and dirt to collect and rust part.

Most evident with passengers or a load in the rear, caousing the wire to contact the brake line.
