Hello,

I need new brakes lines to pass inspection. I did this once before years ago. What are my best options to replace brake lines today?

1) Do they sell brake line kits or is each line bought separately?
2) What tools will I need, I know I need a bending tool and something to flare the ends.
3) Do they sell pre-formed complete brake line kits for the 2004 Buick LeSabre

Thank you,

I am watching a couple of videos. Will the rear lines be easier to do in 2 or 3 sections or can they be done in one piece on the Lesabre?

Not sure on the question, but here's the diagram on the system. Any tubing can be split and joined, but best to do a full line when possible to avoid any possible leaking.

Does anyone know if it has Double flares or ISO Bubble flares? And what kind of fittings does it have?

You've probably already finished this, but I'll reply for the sake of completeness.

I believe that your 2004 has the same lines as my 2001 (according to RockAuto, anyway). I have the GM lines from the master cylinder to the ABS modulator valve, and they have ISO/DIN bubble flares on each end. I don't have the hard lines from the modulator valve to the wheel positions, but the hoses at each of the four calipers receive bubble-flared lines. I doubt that the modulator mixes types, so I would say the lines are bubble flares all around.

Sorry, I didn't take the time to actually measure the fittings. According to some of the part write-ups on RockAuto, the hoses are M10-1, and the master cylinder lines are M12 on one end, M14 on the other.
