Default 95 Bonneville SE Brake Line problems

Hi guys new to the forum and have a questions.

Bought my son a 95 Bonneville so he has a car to go back and forth to school. The motor runs great probably could use plugs but other that that runs good. Drove the car home all good. My son starts driving and the brake light on dash comes on. So I check brake fluid empty, so I fill up and couple hours later son calls and says brake lights back on. I check and brake fluid is empty. Look under car and at the abs module where the lines come out I see two lines that go to rear all rusty and a lot of brake fluid by the radiator. My question is how hard is it? and I know I will need a bender and brake line flaring tool? Where do I get this stuff from? Is there a cheap flaring tool that would do whatever type flares I need? I just need help as I have never replaced brake lines before. I do a lot of other vehicle repairs but brake lines are not one of them.

Any info would be appreciated

Thanks

Brad

Sorry guys did a search at autozone and they have all lengths of tubing with the ends attached so I guess now my question would be which end type do I need?

The ends are metric. I took one of the fittings off and got a few at car quest. I think it was a coil 3/16 with a metric flare tool. The tools aren't that bad.

that must be a problem area on two of my three bonnevilles i had brake lines rust and break right there.I just found good metal(on existing line) cut it with a tubing cutter slipped an end on flared it then took a new peice bent it to shape (if no bender is avail wrenchs work well closed end) put fitting on flared them installed filled fluid bled the system and was good till i got rid of the cars..

Yet that was just me.id say being a 95 if the have prebent full lenght lines buy them and replace em all..But no matter what you do spray the tubes with a rubber undercoat so they last a bit long than origs

my 98 and my inlaws 96(i do the work on) rusted through there too, but whenever i patched something in the past they always just leak somewhere else as soon as the pressure comes back. and to replace all the lines its cheaper to get a coil and the metric flare tool than those pre-bent ones not a real difficult thing. i could see getting pre-bent trans lines,i have, they dont bend good but the brake lines do.
