2000 F150 Rear Brake Lines
The left rear brake line on 4x4 4w-disc has blown a pinhole due to corrosion. The hardline ties into a splitter fitting on the rear axle. The hardline runs across the rear axle to a rubber hose that ties into the caliper. The rubber hose and hardline appear to be a one-piece assembly. My local parts guys don't carry a replacement part. Has anyone else dealt with this problem? I could splice a new section of line in place. Are the hardlines and fittings metric on this trucK?

We'd do it

That does look like one piece, probably why the parts store doesn't have it. Might want to go to the dealer. I don't see why you couldn't splice a line in if you wanted, but it needs to be done right. You will need a double flare tool, brake lines must be double flared. Don't use compression fittings, they aren't safe for brakes. If you're not driving it right now cut the line near the fitting, unscrew it and take it to the parts store. Then you can match up the threads. You will also need a union to screw the lines together. If you can reuse the fitting be sure to put it on the line before you flare it, otherwise you will need to get 2 lines to take a fitting from one.

Well I grabbed the bull by the horns. Pulled the left side line off and went to the see the parts man. Picked up a collection of fittings and adapters as well as copper crush gaskets for the banjo fitting bolts on the calipers. I already had some new 3/16" steel tubing onsite. I was surprised that just about everything on the hydraulic side is still fractional. In any case I re-used the flex hoses and cut back the rotted steel line. Spliced in new steel line and used my double flaring kit for the first time in years. The left side flare fitting at the rear axle tee was the next size up (1/4" tube) from your typical 3/16" line flare fitting. I used a reducer fitting to reduce down to my 3/16" line. In anycase it wasn't too bad of a job. Still not much fun craling around on my hands and knees and fending off the spiders. Since the right side brakeline also looked pretty corroded, I replaced it too. Afterwards I gave the hydraulic system a quick bleed and took it for a drive. It was definitely better and stopped the truck but still not up to snuff. The truck has about 90k on the clock with original hoses and master cylinder. I may replace the master cylinder and front hoses since they are readily available. I've attached some "after" pictures.

I have the same problem, only the hole is next to where the steel line is attached to the rubber line. Any one been able to find a rubber line that will attache to the caliper and have thread to attach steel line. Ford wants $240 for line assy.

Hey nice job. The one side does look a little low. maybe you could take it off again and take some slack out and reflare it. I would put new pads on all corners and replace the fluid while you were at it pads and fluid is pretty cheap. good luck.

In the photo there is a line in and a left and right line out. But what is the other hose for? Vent for rear axle or ? Mine has a plastic valve in the end of it and there is no air flow thru hose. My reason for the question is because mine broke off at the block and I was looking for a place to connect the end with the valve?? Can you advise me?

I know the threads old but I'm currently doing mine at the moment and for anyone chimming in the metal line and rubber hose are not one part. Likelihood that the metal line hasn't fused to the rubber though is another story lol. Under where the rubber hose meets its metal holding bracket they attach together.
