[DeTomaso] Dumb brake line question

[SOBill at aol.com]

Brent,
 
37 degree flares are only for AN (think braided hose) fittings.
 
45 degree brake line double flares (where the tubing wall is  folded back 
to the inside of the flare to provide a double wall  thickness) are used, 
mostly,on older US cars.
 
Bubble flares (where the end of the tubing is pushed back into a sort  of 
bubble, but not folded back to double the wall thickness) are used,  mostly, 
on EURO and Asian, cares.
 
I say "mostly" because until you have the tubing and the part with which it 
 must mate in your hands, you cannot be certain.
 
Bubble flares were invented to overcome the problem that double flares  
often will not seal if reused. Bubble flares are better able to comply with  
the mating surface when reused. The type of flare, the flare nut, and the part 
 with which the flare will mate must all be correct for that type of flare. 
 
Auto parts stores have US and Metric size brake tubing with preformed ends  
in various straight lengths. They will let you search thru their brake 
tubing  rack for what you need. Using these pre-flared tubes, means, after you 
make cut  one end to fit, you only need to flare one end.
 
So many "standards" have been employed, that there is no  "standard." 
 
Ah, the stories I could tell!
 
The main  thing is to keep the main thing the main thing.
Do the best you can with what  your have where you are.
Have fun today!
SOBill

OK,  Not sure where to look this up, but I figure y'all know this off the 
top  of your head.
Are the brake lines on our P-cars flared at 37 or 45 degrees?  Also, If I 
needed to replace a section, what would be the correct size  given that (i 
think) metric line would be pretty hard to  find?
thanks!brent4328
