Chafing, it's never good

right brake line rubbed thru by scat hose not properly secured. Fortunately the crosswind was from the right or things may have gotten interesting.

Properly secured and protective cover added to line for backup. Another item for the checklist at oil change and annual times.

Interesting. I was under my floorboards the other day and saw the same thing. Immediately put some spiral around it. That could really ruin a guy's day.
