Brake Hoses and Lines
I'm in the process of replacing my brake hoses on my 71' Highboy. I am having a hard time getting these hoses off. Does anyone have an suggestions on the best way to get them off. I disconnected the rear axle lines from the bottom of the rear hose. I got the line off that goes into the rear hose, but I cant seem to get the hose off of the bracket. I also tried to break the front hoses free with no success. Is it true flare nut wrenches work best for these?

I don't know about the highboys but on most I've seen there is just a clip that retains the hose end through the bracket on the frame of the truck. You should be able to pry it out with a screw driver.
Line wrenches are awesome for brake lines. I picked up a set of cheapies at Harbor Freight and they've been a life saver. They more fully grip the tube nut and the heads don't flex like an open end wrench might.

Yea it appears to have that same clip your talking about. I was just afraid to go prying in there. I'm going to look into the line wrenches. Also on the bottom of my rear hose there is a fitting that attaches to the axle. The hose doesn't appear to come out of that fitting. Will that come on the new hose?

Inside the vent is a tiny hole that gets plugged up. When this occurs, pressure builds up inside the housing. Sooner or later the pinion and/or axle seals will begin to leak.

So maybe I should just replace the vent also. I just didn't see how the hose came off that. Thanks for all the input guys. I'll keep you posted. Learning as I go here. I'll post some pictures a little later.

another thing you could try if nothing else works to free up the lines is you could cut the line in half and slide on a closed box wrench this will give you more area of the flange nuts to get a bite on to try and break them free. since your replacing them you dont have to worry about the lines being cut also try soaking them with PB blaster for awhile before you start loosening them will help free them up easier
