The brake line that runs down the left frame rusted out today and I need to get a new one. Can anyone tell me if this is the right one.

 

This is for second generation 4 door blazers 1997-2005. Typically they rust out near the rear connection. I bought a similar one from a Canadian company - wasn't cheap - but amazing fit. The union in the center is to install the line onto the frame without bending it (originally was installed with no body on the frame). The entire length of mine just snapped right into the factory clips.

 

While not as ideal, but much cheaper, I just grabbed then from the junkyard from a car that didn't have rust on the parts.
And then you will have extra experience taking off the one in your truck!

 

Copper-Nickel brake pipe, will last longer than your vehicle!

 

awesome thank you. Mine is an 03 4 door

 

You are welcome. I looked it up and you are apparently looking at buying from the same company (Lines to Go). I believe the correct part for your 2003 4 dr is BLC-108-1G. For my 2001 it was BLC-108-1E for some reason. Not sure what the difference would be, if any. Amazon sells one part # for 1997-2005 (without the suffix).
