How can I replace rusted brake lines on my 2000 Suburban LT?

I have just bought 2000 Chevy Suburban 1500 LT model. When I opened its hood, I saw all brake lines are badly rusted. And all dust guards on brake assemblies are rusted out too. So, I am thinking about replacing all brake lines by myself. Is it too difficult to do that? I googled the topic. But, I was unable to find a good answer. I have performed simple maintenance for other cars. And the most complicated job I've ever done was to replace hear core of my 1988 Volvo 240 DL. Thank you so much for your answers in advance.

Brakes are a critical safety issue
the flares on the lines are double flairs ( required by law)
it would be cheaper in the long run for you to go to accredited brake and clutch professional shops and get quotes to replace the steel lines
they have the equipment , material and the knowledge to do the job properly
or you can diy by going to a wrecker/junk yard that handles your make of vehicle and get good rust lines as replacements

SOURCE: break line rusted out

WOW that's high. They are correct to want to replace all the lines, 'cause they could be liable if another one goes right after they fix it, and another probably will. I plow snow, and my trucks brake lines have been changed twice, due to road salt. I would get at least 2 more estimates. It is a nasty job, as everything you try to take off is rusted up bad, but I'm sure u can do better , possibly a private garage. There are stainless steel lines available on the internet, but not sure if your model is available. They cost a lot more than regular steel, but if u don't plan on keeping the car another 8 yrs. go for cheaper steel. good luck countrycurt0

SOURCE: Replacing brake lines

Many issues can come into play when trying to mount prebent lines. First off, they are connected in
many of the same brackets as other lines, (ie.: fuel lines) . And sometimes because of the length and shape of a prebent line, other things such as the muffler routing, fuel tank position, ABS lines,
strut mounting can all " get in the way" of a one piece replacement. And of course all those lines would need bled of air when complete which poses problems if old bleeder screws are bad as well.
My suggestion would be to save the money on a factory bent line , head to or have towed to a
reputable garage and ask if they can service the lines, the experienced techs have ways of freeing
up a frozen bleeder, working around the hazards in the way with aftermarket replacement
brake lines and all the necessary adapters for proper connection. I have many years in the field,
Let the pro's do their job and keep us all SAFE. You wouldn't call a gardener to wire your house.
Ha Ha Ha I applaud your eagerness to fix things, but this is one thing I would let go.

PS Tell them what you have to work with and the quality shops will do what they can to help you.
The money you would spend on Dealer parts shoud be easily enough to more than cover the aftermarket repair.

SOURCE: 2 issues...Brake tube rusted and random cylinder misfire

1. What is the OEM diameter of the tubing? I plan to use plain steel, not stainless. If they use salt on the roads stainless is better, TUBING IS 3/16"
2. Once I get the tube bent, would it hurt anything to paint them with rust bullet? No for mild steel, stainless won't rust though, no paint req'ed
3. So I know what flaring tool to get, what kind of flares are on the ends of the tube? U will need a tool that does double flares, around $60 US, if u have ever used a double flare tool read the instructions carefully.
As far as OD of line, take the old to the parts store and match it, but I think it is 3/16"

The engine issue, best u have a trouble code test run and go from there, any Kragen or Autozone will do it for free, if nothing shows clean the inside of the MAF sensor with CRC brand MAF cleaner, water could not get in the line because there is over 40 pounds of pressure, u would see allot of gas on the ground under the truck.

SOURCE: bleeding brakes 2000 suburban wsith ab

Why were the brake lines replaced?

Sounds like the mastercylinder may have run dry. You have to bench bleed the master and then DO NOT allow fluid to run low, while bleeding brakes...

if master cylinder runs low on fluid and air gets in, almost impossible to bleed with out releasing the lines and bleed master it self.

Hello: Sounds like the system is freezing up. Under the hood passenger side there is a silver colored cylinder about 12" long on or near it is a switch with two green wires connected, When the condition occurs, stop truck, open hood if the accumulator or lines are frosted up (white) replace the described switch. The system does not need the freon removed just unscrew the old switch and install the new one. The new one should come with a new "O" ring. Put a small amount of A/C oil on O ring prior to installing switch.
