Do not let a dealership rape you on this... its an EASY fix.
Cut the brake line where its broken... tkae out all the bad part until you get to good metal. (take bad line into parts store so they can give you correct size!)
Buy a brake line flare tool $10 at advance auto / auto zone.
Buy a piece of line the length you cut out and get 2 female ends to put on your existing line on the car. The line should/will have 2 males. If its females then buy male ends.
Slide the female ends on the line you cut, then put the correct flare on the line using the flare tool. Make sure you put the ends on the right way and BEFORE you flare it. Once you flare it you have to cut off the flare if you forget! lol
Next, just screw your new ends onto your new piece of line and zip strip it up!
Your done!
Dont let the stealership tell you you need $1500 worth of new brake lines!! Its a $25 fix!!!
