Was doing an inspection on the coach and noticed severe wear on the curb side air line. It gets bent pretty good when the wheel is cut hard. Is there a formula for hose length or just go with the same size. When it gets jacked up I am going to look into swivel fittings on both ends and try different lengths and see what i find. | ||

I personally wouldn't use swivel fittings, since I would think that over time they will start to tighten up in the harsh environment of a wheel well. Normally you just create a loop that can go to the steering extremes and place it so that it doesn't rub on anything. The hose is meant to flex and bend in that kind of range of motion. It's also meant to be maintained on a regular basis, which in this case means replacing it before it gets old and crusty and loses its designed in flexibility. Probably every 10 years or so.

Swivel ends will allow the hose to droop down and rub against things, defeating your attempt. You want to tighten the hose ends in such a way that you direct the loop of airline up into the open space between hard components. Sounds like you need a little more length. happy coaching! buswarrior | ||

Over this end of the world you have to have small springs secured to the brake hose then to the chassis or some other secure point to pull it clear of the wheel if there is a chance of the hose coming into contact with the wheels on turns or if there is a chance of any hose coming into contact with any wheel. This is part of our registration requirements. The hose can bend and move around as the wheel is turned through lock to lock or whatever, the spring will hold it clear all the time. Dirk | ||

my '04 has springs wrapped 8" or so from each end, this helps keep the line from rubbing...still one managed to rub and when I went to replace it at my HD truck suppply store i could only find DIY fittings with 4" spring ends. Bought the hose and made an airline...seems to work, no idea if this is allowed though, maybe someone will chirp in. | ||

Thanks everybody again for the replies. I took it off this afternoon and the one on the drivers side looks perfect (i am changing them both) and is 2" longer. Swivel only on the wheel end of the hose and the drivers side had an almost up and down loop where the worn one had the loop almost at a 45 degree angle. i am gonna add the 2 " to the hose and I think i know how to set it. maybe. haha | ||

Well i dident have to have any hoses made up,its a stock hose! I did have to get some adapters as my bulkhead fittings needed to be changed. The original bh fitting was 1/4 pipe. The adapters go 1/4 ips to the male brake line to fit the new hoses. Price of 2 hoses and 2 adapts was 58. with tax. They could have made a 1/4 hose 2 braid to fit but no DOT #'s and one hose cost more than 60.to make. |
