cost to replace all rusted break lines for 2002 Cadillac Escalade?

What is your question?

I’ve had my Cadillac Escalade for 18 years, the center and front brake lines are extremely rusted and have begun to squirt fluid out after the car turned on. The break pad touches the floor when pressed therefore, I no longer drive. GMC states that some of their models’ brake lines (2000-2009) are known to rust after long periods of time and suggests replacing ALL brake lines at once. I purchased a brake line kit from GMC( includes all 5 brake lines) $137, but I’m unaware of what I should pay in labor costs........Please HELP!

What makes this problem better or worse?

worst when engine running, brake fluid squirts out

How long has your 2002 Cadillac Escalade had this problem?

A few months,
