We had a van coming in the garage the other day with a rusted out steel brake line . The line didn't look too bad except for one section but was weak enough that when the driver made a panic stop it blew . We're gong  camping this weekend with our 2001 GMC 1500 HD and 30' trailer . The brakes are so big on this truck, 8 lug wheels , you barely need to  put much pressure when empty to stop   . Anyway started it up in the driveway and pushed the pedal very hard ,, blew a  rear  brake line !   I'm so glad it happened before going instead while towing the camper  . I made a new line from the ABS to the rear rubber hose ,but I want to see if they make SS brake line kits for this model

When one line blows you can be sure the others are close to failing, best to replace all of them and not temp fate.

 

Very glad it was in your driveway, leaves a stain that sticks around a while, the thought is a bit scary, there is the ebrake and when used properly works fine for controled stop but during a panic stop there is no time.

I know GM is making a complete brake line kit for those trucks but don't know if they're any better. Have you used any of the alloy line that isn't supposed to rust or rot? Check around on the prices, they seem to vary a lot. That stuff is real easy to work with too.

I just did the lines in my sons' 96 Taurus. I bought the coils of line and a "bubble" flairing tool plus fittings and flex lines for a little over $150. It was a bear but its done. I tape the new line to the old line as I bend it to assure a good fit. The new corrosion resistant line is more money but supposed to be easier to bend. Take your time and be safe. Good Luck, Rick

I recently replaced the lines on dads 06 gmc, went with the nickel/copper lines, I bought a bulk coil and flared all the fittings, be sure to save the ends at the ABS they are odd and most places will have to order new ones.

I had a rear brake line blow out on my old truck while in heavy traffic. Not fun at all.

I could just imagine how hard it would take to stop my truck with my 3k , 5x10 trailer .  Or when my son was using the truck to haul scrap metal .

GM brake lines in the 99-07 trucks were and are a horror show! No wonder they went bankrupt....
Anyways this is the proper tool for them.

I had a bad experience with my ram. I almost hit a school bus because I blew out a brake line when I went to stop. Scared the crap out of me. It wasn't a close call of hurting anyone but it could of been worse.

I got out and explained what happened and apologized up and down to the parents and the bus driver. They all understood and the one dad let me pull my truck in his garage and helped me clamp off the line so I could get home.

Keith , that's the tool I borrowed from work to make the line . I want to see if premade ones are to replace that one and the rest if not will just make my own .

Back in the late 90's I was driving on the LBJ Freeway in Dallas in a 1980's Buick, had my Son with me at the time. I looked over at him, he was doseing off, and as I looked back up, all I saw was 6 lanes of break lights, You guessed it, pedal went to the floor, rear break line blew. I punched the E brake to the floor and looked for a soft target, which was an old pickup truck. Jacked the bed of the truck up, and bent the Buick bumper into the grille, demolished the grille, but not the raidiator! (The Buick is built like a tank) Limped off the road with the pickup. (Musta been an Ille.... No insurance) because he said I wont't say anything if you dont'..... Limped to the nearest garage and got the line fixed, then drove home to Waco. Oh, My son took it in stride, we were wearing belts, and he learned how valuable those are. He used the car for School transport till the engine gave out.

LMC might make a pre bent stainless steel line kit for your truck,BUT save your money cus if there bent like the factory lines,it may be next to impossible to install them.The reason is the brake and other lines are some of the first parts put on the frame when the truck is built and you would have a heck of a time trying to snake the line in the correct places on a built truck unless your doing a ground up restoration.

I'll bet a dollar to a donut your line rusted out where it's held on with the plastic clips---thats where all the road salt collects.
