On the way to the track yesterday had a semi abruptly stop in construction site causing me to jump on the 06 c5500 super c much harder than normal.

After I immediately noticed a difference in brake pedal, pulled over and found what in expected a blown line about 1/3 of the way back.

I'd like to replace all the hard lines as even though the RV is garage kept in winter, the lines all show a little rust.

Prob is I can't find the lines premade anywhere.

Again it's a 2006 kodiac c5500 8.1L motor

Any help would be appreciated in locating the hard line kit.

I looked also. Highest i have seen are for the 3500. I will keep looking also.

Contact classic tubes they may be able to make them for you otherwise get a spool of stainless and start bending

I've replaced some brake lines recently and used nickel/copper lines. It sure is easy to work with and look like they won't rust.

Stainless is a MF to deal with. Did all the fuel lines in a 24 foot MH in stainless. NEVER AGAIN

This! You can get large rolls very cheap. It's soft, easy to bend and flare, and cheap.
Don't use stainless. It doesn't flare easy, hard to seal, and even harder to bend.

Jesse, I can't help you, but just wanted to say hi and hope all is well with you and the family.

Thanks for all the comments. Sorry I did not report back sooner.

I got a roll of NiCu this weekend and redid all the lines with the help of a buddy. Went pretty easy and good. One 50ft roll did it all. I feel much better. Replaced drivers front hose as it looked suspect a little.

Replaced rear rotor - that was fun is the entire axle needed removing - really wasnt that difficult other than the size and figuring it out. Now I could do it in prob 30min. Replacing that sides caliper too. Just waiting on caliper and hose to complete job.

Something that everyone should inspect on their rigs. I looked several times and saw what appeared to be surface rust. What fooled me was where these failed they had the factory tags on the lines which hide and promoted the rust in these areas. Every place there was a tag the rust was very heavy. Another brilliant play by GM. OTherwise the rigs undersize for a '06 is perfect. It only had 24k miles on it.

On a 15yo vehicle if replacing 1 brake hose I'd shoot the load and replace the other. Most of the hoses don't break or leak they tend to collapse internally and cause a brake drag.
I've been very lucky with brake line failures. The last 2 on my tow vehicle happened in the driveway or the shop. I won't fool with steel any more after having replaced lines on a relatives truck and having them rust out again! Why American manufacturers won't switch to NiCo lines to solve this problem is beyond me but I won't use anything else on a street driven vehicle.

Is this a road salt thing? I have never heard of brake lines rusting to the point of leaking or worse yet blowing out.

Yes, it's a road salt thing, at least for my area.
What seems to have made it worse is a liquid brine solution that they spray before a storm to keep the snow from sticking to the asphalt. It's cheap compared to the cost of salt.

GM should have been on the hook for this screw up.

Ni-cop is all I use any more. First time I used it was around 6 years ago and no issues.

Holy crud guys. There is no way I would live somewhere that that would happen. Now I get it.

Curtis in the North East in the winter there is more salt on the road than snow--I have one sitting in the garage right now with rust failure of both the brake lines and the fuel lines. About lost the motor home once because of a rusted out brake line.....salt!!!!!

Kimd of limits where you can live any more. Every state sprays all kinds of stuff now since they have to keep the roads clear. I'm in TN and it's not as bad as further north but brake lines rust. I won't even look at a vehicle from Virginia that's for sale.

Well I can say it's never been a problem in Oklahoma. We only average 10" of snow a year and rarely have more than 3-4.

Now I get why Yankees are so grouchy all the time. Just kidding you northern peeps.

Guess that tells me not to buy any vehicle that is from Tennessee also.

This particular vehicle was never to my knowledge run on salt roads and stored inside during winter.

Everything else looks good - except the lines.

I did replace every line with Ni-cu. cut them out one by one and pulled new. Wasn't that bad as there is plenty of room to work under it with the leveling hydraulic system up on high - with safety stands also.

GM if you do a search had LOTS of lawsuits on all their vehicles during this time. The guy helping me said they have a coating on the new ones - and there is a solution that you can buy and spray on things that really helps prevent rust for a long time.


During the summer months I do park the RV 50% of the time in the grass - so perhaps that created some of the issue. Shouldn't be a concern now with the NICU
