Brake lines rusted...blow out!!!

Brake lines rusted...blow out!!!

Postby thirdgen [OP] » May 23 2011, 5:58am

I was driving my truck on Friday and I was stopped at a red light. I had my foot on the brake pedal, and after a few seconds, it felt like something popped, and the pedal went flat to the floor. I drove it home like that, and I found that the line coming from the master cylinder to the I think it's the ABS module in front of the gas tank, rusted through and blew out.
Anyonen ever have this happen?
My truck has 182,000 on it, but I googled this problem and a few other people who have had 2000 Silverado's and Sierra's have had this issue also, but with wayyyy less mileage.

Yup been there-twice, however the vehicle was of a different brand. In this case I thinkg brandin matters less than the geographic location of the truck. If you’re in a corrosive environment where rust is an issue than this is an rust on the line is a concern. A 12 year old truck with near 200,000 it can happen. These brake lines are under serious pressure (depending on system 1000psi +-) and degradation in the lines and a weak spot can let go. Like I said I have had this happen twice, and I walked away safely both time I have learned Never ever mess around with brakes. Keep them top of priority list. It sucks if you blow a tranny or your engine craps out, it is real expensive, but if your brakes go out… Enough preaching-sorry standard brake speech I give everyone I meet because I am lucky enough to meet them! Glad your ok, just have it all checked out and replace anything funky.

Wow, never heard of a line rusting out and blowing, have had lines blow but my truck was about 15 years old at the time, not much salt up here though, just a little on the roads in the winter. Glad to hear nothing bad happened.

mine never blew out, but while having the abs module serviced the stealership, had to replace a couple of the ends because they were severely damaged and ended up twisting the lines and breaking. So a line failure while driving was inevitable, I was just lucky it was found early. The truck spent its entire life in Texass and had less than 100,000 miles at that point. Environment, road salt, ect... did not seem to be the source.

The FED is investigation 6.2Million Chevy's mainly the 2000-2001 Suburban to the 99-03 Silverado for poor quality brake lines. I contacted the NHTSA and the NTSB at least document it with them. They can possibly issue a recall on the brake lines issues. The lady did tell me today that they have received lots of calls all about the same time regarding the brake lines on those particular models. I might 2000-2500 Complaints in an 8 month span of the same issues. Brake lines corroded and burst. If GM didnt skimp and put stainless in the vehicles this wouldnt happn. But no, they put junk steel lines in to get $.05 a roll.

Same thing happened to me today. I was at light felt the pop, petal hit the floor. It blew out left rear side. Looked like just past junction fitting so it might be easy fix. Anyone know if these are prebent lines? Or is all the stuff retro fitted?

You'd be best off pulling the whole line out and replacing it. I belive you can rent the line bender and flaring tools from most auto parts stores. Bending lines is not hard to do if you have the right tools and good stainless steel line.
