Discontinued PN 47326-04050

Hey all, I discovered a rather unfortunate issue when I crawled underneath my truck to diagnose a shudder I was experiencing upon slowing to stops. My driver's side rear Bilstein 5100 shock seems to have unscrewed from the bottom mount and broken through the boot. As you can see, it also completely flattened the hard brake line on that side, which is what I believe to be causing the issue I'm experiencing with the shuddering. I called a Toyota dealer and was able to figure out that the part number I need is 47326-04050.
The next unfortunate road block I discovered is that this part has been discontinued. I did manage to find it on Toyota Parts Deal and Auto Parts Prime, but both are charging about $330 for freight shipping (on the part that costs about $30). I'm hoping someone here might have some experience with replacing these hard lines for less than I'm seeing through these genuine parts dealers. Any recommendations and help with this issue would be greatly appreciated!

 

Most folks just make their own brake lines- it used to be hard to find metric fittings, but that may have changed. Although- you can probably salvage the fittings. That line only runs from the drum to the Y-fitting on top of the axle housing.

If that's not your thing or you don't have access to a garage, etc... Then it would be best to call some shops around you and find a place that can custom make one for you.

Edit: What fluid is leaking? If it's brake fluid, you should stop driving it, and get that plugged up right away. If you don't you run the risk of emptying or damaging the master cylinder and ABS if you have that.

 

If I were to salvage the fittings, is there a good way to remove the damaged line and cap the Y-fitting? I don't think I'd have the know how to make my own brake, but if anyone has any recommendations of shops that do that, I'm in the Denver area and would greatly appreciate it!
As far as that fluid goes, it was just a bit of overspray from the PB Blaster when I hit the rear diff drain plug. No leakage from the line, I did catch it in time to avoid busting it completely. However, I do wish I had more warning that the shock had blown and I may have been able to remove it before the brake line even got damaged I'm the first place.

 

Shocks have a roughly 30-50k life span, and should be visually inspected on each oil change.

 

Making your own hard brake lines is not that hard. You can buy the lines online and cut them to fit. Then you bend it with a tube bending wrench. Make sure to debur the edges inside and out. That part is very important. It's easier than you think. Might as well splurg for stainless steel lines.

 

Definitely a live and learn kind of a lesson. I guess I never realized that the lifespan is so short on shocks. But I'll make it part of my typical oil change inspection.
As for making them, that doesn't sound so bad. I'll look up some videos on it. I guess my question would be, how would people recommend finding the correct fittings where it connects to the Y-fitting and then to the back of the drum? I want to make sure I have it right before I go in there to change it out.

 

A quick search on this site turned up some results. Some of the threads suggest places to buy the tube and fittings.

 

The Copper/ Nickel brake Tube is so easy to work with .

Federal Hill is my Go to for brake fittings and tubing.

Get a decent double flaring tool .

Good luck.

As others have stated creating your own brake lines is not that hard. I had to do it out of necessity as well when the rear drivers side line on my Ford F250 CC broke in half by the fuel tank. Purchased some tools from Eastwood, Line and fittings from NAPA and a couple of YouTube videos later I was off and running creating my own brake lines.

 

I appreciate all of the tips on making my own, so I'm definitely leaning in that direction. With a double flare kit and watching some videos, it seems doable.

Would anyone be able to tell me what fittings are needed? It'll be one for the backside of the drum, and the other for the Y-fitting. Just want to make sure I have the right ones going into the job!

Also, here is the double flare kit I found on Amazon. Seemed to have good reviews, but if anyone has any recommendations there I'd also appreciate the advice:

Depending on the length you need, you may be able to go to your local auto store and find a pre crimped section with the fittings already on it. You just bend by hand and bolt it on up. Aside from that, everything's already been said. I'd make my own or have an independent shop make you one since they already have all that stuff laying around.

 

Are the fittings for both ends of this line pretty standard across hard brake line? My worry it disconnecting it only to find I don't have the right replacement (but I suppose I could just reconnect my flattened line in between if that happens).

 

Take this with a grain of salt as I can only speak to second gens, but on mine, all brake line fittings across the entire truck are the same M10x1.0 flare fitting. I imagine first gens are similar but do your own research.

 

I would also suggest some rubber stoppers (get an assortment from Amazon) Once you disconnect the line, jamb a stopper in there so you can take your time.

 

Had to make
3/16” line from advance- the copper nickel about 13$




I took a hanger and formed the line from stock and took it to the hydraulic hose local shop and they bent flared it for $29. Didnt have a kit or experience and probably not worth it to get one.

the rear passenger side is still available and I do have one in a box if needed haha

 

The ones i received from the advance (copper/nickel )
fit fine, i dbl checked them with the spare cylinder I ended up not needing.

 

Awesome write up @TWJLee, that's just what I needed! I am looking at getting this Brake Line from Advanced Auto Parts and then borrowing a co-worker's tube bender to form it:
https://shop.advanceautoparts.com/p...UALI12r992FwiIBSTUhoC6AcQAvD_BwE&gclsrc=aw.ds

Seems to have the right M10x1.0mm fittings, but I'm just not sure on the length. Will a 20" piece of Brake Line be sufficient, or would it be safer to get the 30"?

Thanks for checking and confirming the fittings on the spare cylinder you had! This has all been super helpful and I'm feeling much less hopeless about this repair than I felt when the dealer I called said, "Sorry, that part is discontinued".

 

Use a piece of string to trace the brake line along bends from end of fitting to end of fitting, then measure how long that is

 

Is your rear lifted, and if so, how much?
