Hello!

I need to know the tread size and flare type of the steel brake lines of my 1991 Buick Park Avenue.

Can anybody help?

I have now found this offer:
https://www.finelinesinc.com/buick-lesabre-1992_1999

This company sells prebent brake lines for a Buick Le Sabre 1993-1999.
I think these are the same brake lines as for my 1991 Buick Park Avenue, but I am not 100% sure.
Can anybody confirm that the brake lines are the same for both cars.
They are both GM "C" Platform full size automobiles with "Teves Mk. IV" anti-lock brakes, am I right?

Unfortunately, it looks like none of the metal brake lines are available from GM. 🙁
 
You are correct HotZ28, the brake lines are not available from GM.
I have compared both (91 PA and 93 LeSabre) brake line drawings.
Apart from a few neglible differences, both systems seem to be the same.

I guess I am going to order a full set of brake lines for a 93 LeSabre.
Lets hope they will fit my 91 PA.
 
If you have to use parts store brake line, I suggest the copper-nickel instead of galvanized steel. Flairs and bends much more easily without kinking and very corrosion resistant. Little more pricey though.
