my brake pedal was acting funny so i put brake fluid in, when i pump my brakes the fluid comes out of the line somewhere under the driver side pretty good, do i have to replace my lines or can i fix the leak???

 

FIX it....I would suggest you do not drive until it is repaired.

Several ways to preform the repair. Not sure if you are doing this or taking it somewhere. Just know that if one section rusted out, I'd bet other sections are not that far behind.
