My 2003 Tahoe has a leak in the front-to-back steel brake line and I'm considering replacing all the lines with pre-bent stainless. Has anyone on this forum replaced the front-to-back brake line? Can you access all the clips on the frame, especially where the gas tank is? Thanks

 

I think I'll have to replace all the steel brake lines. I can't get a flare nut wrench onto the fitting that goes to the rear brakes at the proportioning valve without removing some of the other lines and I doubt that I can remove them without replacing them. Seems like the best option may be to cut all the lines at the proportioning valve and remove each of the line nuts with a 6 sided socket. Even then there is not much room. There is a bolt holding the proportioning valve to the frame and I'm wondering if I remove this can I remove the valve? Is there an electrical plug connection that I need to disconnect?
