Default 1995 bonneville rear brake flared fittings

*1995 Bonneville SSEi with rear drums*

My rear brake hoses (the ones that go from the flexible one to the cylinders) are very rusted and I'm starting to feel a little sponginess in the pedal that suggests they are probably going to leak soon (that or the flexibles, but lets start with that!). They are missing a layer of steel at several places.

What is the type and thread of fittings that go there? metric bubbles or imperial double-flares? 3/8-16, M10X1.0??

On my Caddy they were bubbles in the front and double-flares in the back so I'm asking first this time!

Well I bought 2 X 8" hoses with 2 new bleeders AND a one-man bleeding tool. I can't wait to try it out!

Well, to my great dismay and even though the dealer and you said they were double flares, the fittings were bubbles... I had a great surprise when I took the old one out...

Guess I'm out of luck : I replaced the lines yesterday and bled the brakes with a one-man bleeding tool I had purchased ( which worked out great BTW )...

When I pressurized with the engine on, I blew a line from the master to the ABS module...

I noticed they were all rotten to some extent so I sent the car to the garage to get all the lines changed.... sucks...

thats what always happens, i never just do one line, i get coils of line and a bunch of fittings and do them all. it doesnt cost that much more and its worth the work knowing you dont have to worry about it. i dont send my car to the shop, i dont trust anyone anymore especially not with my brakes.

I understand you perfectly, however the " I need it for yesterday " factor played a great role in me sending the car to the shop.

Wish I had a garage, air tools and all those nice things older people (or people who didn't waste years at school XD) seem to have!
