SV rear cross-over brake line

I believe this may be an anomaly, but i have to ask anyway
While disassembling the rear-end, brakes and leaf springs for rebuild, I randomly noticed that the flares on each end of the line were different.

Right side is a bubble flare.
Left side is an inverted flare.

The self adjusting brake cylinders are definitely standard flare which requires a bubble flare in the line.
As I continue to examine the forensics, it is clear the car is incredibly untouched. Included the date coded Armstrong shocks.
That being said, I am assuming this is the original brake line.

So how in the hell would this have ever held hydraulic pressure?
This cant be normal........right?
 
You are correct that both ends that connect to the cylinders should be bubble flare. Even though it looks original maybe it was replaced years ago and could the inverted flare have had enough force put on it for the metal to "flow" and seal even though not ideal? I don't know, just wondering.
 
Also on my Series V when I replaced all the brake lines & hoses I added a tee in the rear line & put a bleeder screw in the right rear cylinder. Some people here in our forum think that's a bad idea because it's not original, the original works ok and it's adding more sealing joints. But I guess I'm old school and expect each wheel cylinder to have a bleed screw. Also I'm using a 0.75 bore master with no booster so this means longer pedal stroke and I wanted to minimize any chance of trapped air. The tee needed inverted flare.

great feedback JR.
 
First off, S V Alpines have two different rear brake configurations.

1) Self Adjusting

2) Manual Adjusting.

I'm not sure about #1 self adjusting... but think they use

the same lines....

But the #2 Manual adjusted should have the same

configuration as a Tiger, with only one bleeder on the left.

Tigers have the crossover line with bubble and flared ends.

The wheel cylinders have 2 ports, 1 that can be used with a bleeder

OR a Bubble line.

And the other port with a flare seat.

I figured as much.
these are auto adjust Dan
at any rate Ill have to remake this line with bubble flares
 
You may want to investigate how bad the self adjust ones are. I intentionally put them on my car when I restored it. Big mistake. I did everything in the book to try to make them work right and consistent. I gave up. I was going to go back to the manual adjust ones, but decided to go to the disc brake kit. Huge huge improvement.

Rootes offered the self-adjusting brakes beginning with SV production but bailed on the idea about midway.
