Hummer H3 Brake Lines

[jphh20]

I have been going through my 06 H3 and installing the Rancho lift and upgrading some tired components along the way. I live in CT and winters have been tough on my rig despite all the times I

wash off the calcium chloride. I did notice that my front brake lines are taking a pretty good beating and I was concerned about the amount of rust I saw underneath the rubber insulation. This is located between the control arm connection and the caliper itself. I tried doing a search to see if this is a common problem or suggested upgrade out there and figured I would throw up a post to gather some other thoughts. I did stumble on these brake lines but I do not have any experience with this design on the H3. I have attached a quick picture and you can see the rust coming out from the insulation on the upper part of the brake line. Should I be concerned?

Any suggestions?

Thanks

I have not heard of common failures here and the fact that it took 9-10 years to appear suggests that the OEM brake parts have done their job. I think I'd just stick with OEM and ensure that you have a proper fit.

Thanks alrock, I had similar thoughts that they have performed well over the years. They are working just fine now but recognize that they will fail soon. OEM it is...

Thanks again

I seem to remember an advisory from GM back in 2012 about H3's driven in salty conditions. Covered the same thing you found out. I don't think it was a recall, but GM was replacing parts on those vehicles in that rust belt. I was living in sunny Texas at the time and didn't pay much attention to it.

Those crown brakes lines work well with the Rancho and SOA. I used them and I think 06H3 did too.

Yeah I remember the rusty brake line advisory too. The stock brake lines (the rigid ones) on the H3 are tough as nails....very hard to work with and impossible to flare. I've done lots of brake work on them and the biggest issue I have come across is that the end fittings like to seize onto the tubes. This usually results in twisting the tube in half, or rounding off the flats of the fitting. PB Blaster helps but sometimes it's a lost cause.
