Local auto parts show the part that fits is 16 1/2 inches. That's too short. The one I took off measures 20 1/2 inches. Is there anyplace that I can order by length. Not all parts places even list the length
Thanks in advance.
Jim

All three are the same hose, R and L front and center rear. $19...18 1/4 long. I believe AKA Dorman H13841....$8 Amazon......$6 RockAuto Probably all made at the same place. The Peoples Brake Hose Factory, R.O.C.

How much flex should I allow for travel?

There is a "T" that is clipped/bolted onto a bracket on the axle tube. That T allows for a left and right hard line to wheel cylinders. The hose goes from that T to a bracket on the frame. On that bracket, the main brake line coming from the front is attached to the hose. I'm sure you know all this. Never hurts to be sure.
If you or someone has changed brake line routing or geometry, I have no info. You will then have to find a hose used on some other truck that has the correct end threads and the length you need.
The flex you need is how much travel there is as axle extends away from frame. (in a pot hole). Jack up frame, let axle sag in midair (tires off the ground). Then you will know if hose will be long enough.
Be sure to buy it at O'Reilly's so you can take it back. Don't order it online until you are sure.

When reordering from AutoZone they gave me the same part # as what I purchased. Come to find out there was a 16 inch cable in a bag that should have had the 18 inch. I reordered it. They said it would be in by 1:00. After getting jerked around all day I cancelled the order and ordered from NAPA.
The cable you identified should be ok. I didn't think about it but the truck is on a lift and the axle is down. So that should be the extent of the travel. This truck has been fighting me all the way and I'm just starting.
Thanks to the Stovebolt for all the help.

NAPA looked up the rear hose by length and came up with pn 25629. It fit perfectly, length correct at 20". | | | | | Joined: Mar 2002 Posts: 9,115 'Bolter | | 'Bolter Joined: Mar 2002 Posts: 9,115 | I had the same problem when putting together my 1 Ton. The old hose which was ancient was tighter than a guitar string! Since I was running all new steel lines I made the change there to allow the rubber line to fit. I believe I bent the bracket some. | | | | | Joined: Mar 2010 Posts: 10,280 Renaissance Man | | Renaissance Man Joined: Mar 2010 Posts: 10,280 | B A R T, A M O S.

Thanks for that part number. The 18 just reaches but is real tight. Think I'll buy some peace of mind and order the 20.

| | | | | Joined: May 2005 Posts: 8,983 Sir Searchalot | | Sir Searchalot Joined: May 2005 Posts: 8,983 | Keep in mind, that part number has different thread size than the one I gave you. The one I gave you is the correct hose for a stock 1955.
Napa 25629 threads: 7/16-20 and 7/16-24.
BH13841 threads: male-7/16-20 and female-3/8-24
3/16 SAE brake line has a 3/8-24 flare nut and 1/4 line has a 7/16-24 flare nut. So you will need 1/4" brake line going to rear. Your "T" on the axle tube will be for 3/16 line going to left and right wheel.
I buy the premade lengths available at FLAPS.

It would have taken 5 days to get here. I bent the frame connector a tad and am using the one you suggested.
Thanks again guys.
