When installing new Toyota flexible outer brake lines (hoses) it looks like the large lettering on the new hose should be oriented up and the bango fitting pointed toward the rear of the vehicle for it to line up to the connection and locating hole for the banjo fitting once the caliper is put back in place. The hose can be installed 180 degrees the other way but then the banjo fitting faces forward and looks like it won't fit properly. Does that all sound about right??

Can't get the PS hard line connection into the new flexible hose; it was also difficult to remove. It looks like the threads have been flattened when the hard line nut was last ?over-tightened down against the cone inside the hose connection. The DS hard line coupling went right back in to the new hose no problems.

The preferable way to deal with this is with a die from a tap & die set to correct/chase the threads. Whether you can get the size you need (and the $) is a different issue.

Other things you can do:
1. Get a nut and slowly screw it onto the fitting to chase the threads, back it off, and repeat a few times.
2. Slowly screw the brake line on (and hope for the best), taking care your not cross threading
3. Buy a new fitting, cut the hard line and use whatever flare tool is necessary to fix the new fitting on.
4. Buy the hard line

You'd think option 4 would be the best, and it may be. However I don't know if Toyota sells the hard lines pre-bent. My experience has been with german cars and the hard brake lines I bought through those dealerships were straight & I needed to bend them and fit fittings on them.

Nothing's easy is it?

(edit: another option is to try and find a used hard line that's pre-bent for whatever hard line your replacing)
 
Nothing easy for this job, a surprise at every turn. I'll try to get a replacement from Toyota or a generic piece and connections at the parts store in the morning, anyone know the threads of the nut, 8mm x 1.0mm maybe?

Well, I hope you can just use it as is. Perhaps put some anti-seize on to lubricate the threads a little.

I had to replace a brake line on the wheel nearest to the master cylinder at one time on a different vehicle. Duplicating all the spirals (to ensure the left/right side lines are equal length I guess) was a PITA, and didn't look at all as nice as stock.
 
No one had that section of hose, nearest Toyota part is a week away and after taking out the section of hard brake line (pipe) I found the other nut was also damaged by someone overtightening it also. Took the line to a local brake guy who was probably close to 80 years old. He studied it a bit then shuffled off to a grinding wheel and with his half crippled hands ground off the flared portion of the nut that was preventing the nut from screwing into the flex hose and he did it without damaging the threads or the pipe, amazing. The value of years of experience and he didn't even want to charge me but I gave them enough for coffee and donuts for the rest of the day. When I got back home I cleaned up the threads a bit with a brass "toothbrush" and brake cleaner, blew the line out and connected it up to the new flex hose, no problem, the nuts just went in a thread or so deeper than before. Compare the photos above showing the stretched/flared nut with the photos below after grinding the flared ends off.

very cool fix. Nice to find an old-school craftsman who knows what he's doing, even something simple like this.

BTW, those calipers look nice!

;)

and you're right, nothing on these trucks is really easy to work on, a surprise at every turn.

I guess that could be some justification for what mechanics charge to fix these things.
 
Cool, finally a happy ending. :) I didn't realize the flare was causing the issue. Perhaps I assumed too much about it being the threads.

Here's to a quick finish.
