Silverado LS 6.0L

  • Automatic transmission
  • 97,000 miles


All brakes lines needed to be replaced! Due to corrosion the brake fluid became contaminated. This also caused

a failure in the brake slave cylinder.

brake line failure

My wife and I were driving home a few nights ago. When approaching and intersection the light turned red. I pressed on the brakes to stop and the brake went to the floor. We were out in the middle of the intersection before I could get stopped. Thank God it was late at night and there was not much traffic. If it was in the middle of the day we could have been seriously injured or even killed. I am glad it happened at a slow speed an not on the interstate and no one was in front of us. I pulled over as soon as I could and I could see brake fluid running out from under the drivers side door. I have now going to have pay for a very expensive repair to have all of the brake lines replaced. For God's sake the NHSTA needs to issue a recall on the trucks before someone is killed. I would have never purchased this truck if I had know of this problem beforehand.

Silverado LT 5.3L

  • Automatic transmission
  • 125,000 miles


Hello! It's me again, BANANASTAN24! Yesterday, my 2003 Chevy Silverado LT 1500 brakes failed again! God must have been my co-pilot, as I nearly crashed into a Minivan full of kids, just getting out of school. Thank God again, that I had new rear calipers, rotors and emergency shoes installed in March. I got a reject Mass State inspection sticker for faulty rear emergency brakes. I already replaced my front disc brakes with SSBC tri-power calipers and slotted rotors last year. They were the best $1500 bucks I ever spent! I also installed stainless flex brake hoses to all the calipers.

Well all that money and work was useless as the factory brake lines were inferior. The lines from the proportioning valve forward along the frame rail into the engine compartment seem to blow out first. You can almost see them rusting away as you watch them! I just ordered an aftermarket stainless replacement brake line system from ClassicTube for $350 bucks, but my mechanic wants $1200 to do the install! He says it would take two days to do the job. I love my truck, it's paid up in full and I've invested a lot in aftermarket accessories. I'm looking into a new 2015 Ford F150. First thing I looked at, were their beefy plastic coated brake lines. Again, I want to thank God that I didn't kill any children or Myself or Family! "F**K! the NHSTA and GM! I think there should be a class-action or civil suit against them! You can thank Obama for bailing out GM at our cost! Mitt Romney was right, GM should have gone bankrupt! (Which they actually did in 2008).

Front caliper was hung up and when lines were bled a line broke on the frame. Because of heavy rust the dealership said all break lines and hoses needed to be replaced. Also had to have all calipers replaced as the bleeder valves were rusted off. Previously front left and rear left lines had been replaced.

Silverado LS 5.3L V8

  • Automatic transmission
  • 85,000 miles

I bought this truck from a used GMC dealer in the area. The brake lines are completely rusted, no brakes and had a extended warranty on this truck. I took the truck back to the dealer to fix, they refuse to fix it because they felt it was too dangerous. Informed to find another auto shop to work on it. They sold me this rust bucket and do not want to even fix it.. I am done with GM, this will be my last.

Silverado 5.0L V8

  • Automatic transmission
  • 150,000 miles


Had this truck in for inspection, I knew I had a bad abs sensor, but what I didn't know was the brake leak at the left rear wheel. Upon further inspection of the brake lines they were found to be all corroded.

Is this the first time Chevy has ever made a truck for the snow belt? You mean to tell me these great GM engineers didn't know what salt and water would do to these brake lines? I've never seen such professional incompetence! Thank god they're not aircraft engineers, they would have great difficulty designing those plastic kids cars.

My daughter has a Dodge van a total rust bucket, the other day I was behind a Lincoln pickup truck you'd think it would be top of the line but I could see the rust coming through the rear bumper. American auto manufacturers are selling us sh*t and then wondering why foreign cars are out selling them. Of course its the labor unions and not they're multi-million dollar salaries. But don't worry the TV ads are telling us what we need to know . . .Chevy Tough! BULLSHIT!!!

Silverado HD V8

  • Automatic transmission
  • 125,000 miles

Brake line broke, lost brakes while driving down a hill...fortunately I was able to stop by putting truck in park (emerg. brake did not work). This is the second 2003 chevy vehicle we have that the brake line broke while driving. Not only could we have been seriously injured, innocent people could have been as well. Chevrolet and GMC need to be held accountable for their vehicles. My vehicles are well maintained (still driving a 78 chevy blazer), this should have never been an issue. My 2003 Chevy Silverado has been a real disappointment due to various issues, i.e. paint blistering, rusting issues, electrical issues We are a family who has trusted and only bought Chevy/GMC vehicles, not any longer!

Silverado V8

I can't believe all our brake lines rusted. Our brakes failed and risked my family's lives. We were lucky to have made it home. The brake light NEVER came on. Just felt funny one minute and the next, no brakes. This is after Chevy recalled the dashboard. I will NEVER buy another Chevrolet. People are going to die if Chevy is allowed to make such junk.

Silverado RegCab 4wd 4.8L

  • Automatic transmission
  • 43,800 miles

The lines running from the master cylinder along the driver front wheel well corroded through and the lines ruptured causing complete failure of the brakes along with squirting brake fluid all over the catalytic converter. Fortunately this occurred in my drive way. The only way to stop was to use the parking brake. I did the work myself. It took two weekends to complete. Parts from LMC Truck parts were around $600.00. I would hate to see what a shop would charge. I am saving the parts in case there is a recall.

Silverado 2500HD Crew Cab

  • Automatic transmission
  • 86,000 miles


Driving on highway and this guy cuts me off, I hit my brakes and the pedal goes to the floor, I almost rear end the car. Managed to slowly get home avoiding traffic, and see that my brake fluid is spewing out all over the driver side front wheel well. NHTSA shows an investigation in 2010 but apparently nobody cares to fix this problem until someone gets killed. Recall now!

This is bull. GM needs to grow a pair and fix this common problem. This is my first domestic vehicle and after 10 days of ownership I'm not impressed.

Complete brake line failure as a roller backward down a hill. Had to have all line replaced by stainless lines. What kind of junk did Chevy use? Really disappointed in Chevy's decision to use cheap lines.

Silverado V6

  • Automatic transmission
  • 33,100 miles

No warning of impending failure! Came out of store well after engine had cooled, put foot on brake to shift into drive, and pedal went to the floor! Investigation showed pit hole in left front brake line, right under master cylinder. Sprayed brake fluid on exhaust manifold. If engine would have been hot, there would have been a fire. Further inspection revealed all brake lines (4) under master cylinder, have excessive rust flakes. The failed line had pitted through from the exterior rust on line. Master cylinder has never leaked, and this rust is excessive on about 18 inches of the lines, which is very close to the exhaust manifold. I wonder if the heat had anything to do with it? Otherwise, I can see no reason for all the lines to rust in that short space. Does anyone have an explanation?

Silverado ES 6.0L

  • Automatic transmission
  • 18,024 miles

the truck only has a little over 18000 miles its a 2003 already replaced rotors and pads now rotted brake lines paid cash for the truck new $30,215.05 out the door and i am really starting to regret it a very good friend tried to talk me into buying what he calls a real truck a FORD MAYBE I SHOULD HAVE LISTENED!!!!!!! THANKS GM AND DOUG CHEVROLET IN AKRON OHIO NOW I HAVE A LOW MILEAGE TRUCK THAT SUCKS!!!! P.S. MY GOOD FRIEND HAS A FORD THAT HAS 292000 MILES AND HAS NOT HAD TO REPLACE ANY BRAKE LINES WHY IS THAT!!!!!!!!!

Update from Apr 29, 2009: 2003 silverado at 16000 miles had to have speed sensors at the front wheels replaced that cost real close to 400.00 dollars i think it is crazy that i have all these problems with this so called truck. I had the truck rust proofed like the dealer told me to when i paid for my $30,215.05 what i thought was A GOOD TRUCK. WHY DID MY BRAKE LINES RUST OUT AFTER I PAID ALL THAT MONEY FOR RUST???? PROOFING, THANKS DOUG CHEVROLET FOR THE WORTHLESS ADVISE THAT IS COSTING ME PLENTY. And to the worthless GM ENGINEERS the inner fender well on the left front that left an opening for salt and whatever to get in and cause the problem of rusty brake lines THANKS SOME HOW I AM STILL ALIVE. MAYBE I SHOULD HAVE BOUGHT A FORD!!!
