Hey guys, I own a 94 Cadillac Deville 4.9 L. Car is in great aesthetic condition. Unfortunately I was driving around campus and my brakes gave out. The break line started leaking everywhere. The leak was from under the driver side rear door. I took it to a mechanic and is asking 700 for new lines and the labor. He said that all my brake lines are in rough condition. I wouldn't disagree, but is it common for the lines to go that quick, the car has 120 000 miles. I have a close friend that could do the work on my car, at a friends garage. The only thing is that I'm not sure what tools I would need to do the work. My friend rarely works on American cars, if someone would please tell me all the tools that I would need or should have on hand to complete this job. The brake lines and parts I found online and at a dealer for about 100 bucks. Any help would be great, thanks.

Take a look for yourself to make sure you aren't getting hosed. IF the lines are all rusted out, sure, I'd replace them all. If one went out, usually the others are near failure as well.

There is one possibility on these particular vehicles. The brake proportioning valve is in the location that you describe and is a fairly common leak point. Make sure that it's not as simple as that before committing to all of the brake lines.

Brake lines rusting out is due to salt on the road rather than the type of car or age of the car. Over here in California, I never hear of that problem.

Yes, of course. Just seems that I see the brake proportioning valve rust and leak before the lines themselves on these particular vehicles when the conditions are right. Since I am in WI, I see it a lot.

Sorry for the misunderstanding. I wasn't implying that they ALL rust and leak. With the OP located in CT, I think it can be assumed that salt/rust is an issue.

All that is needed is brake line a flaring tool and a few wrenches and sockets. It's not a fun job but it's not rocket science either. If you shop around you may find a more reasonable quote.
