A TV that are primarily used for towing and sits for long periods of time between use is more susceptible. Brake fluid absorbs moisture and unless the brakes are used on a regular basis to heat up the fluid and evaporate the moisture, it will corrode the lines from inside out. After my last line blow out, I replaced all lines with copper impregnated lines. About 15% more for parts, but worth it.
