Thanks, I didn't know exactly when, but knew it was so by 1970.
Dad had a brake leak with a 90's Cadillac, was telling me he lost
all brakes. He didn't understand why the did away with the dual system.
He's not good at explaining, so (in my 40's)
"Dads wrong about that, no way they would do that?"
Fast forward a couple years and my wife's Caravan blew a line.
"Hmmm, this must be what Dad meant."
A few years later my Junker Subaru popped one.
Got it home, filled the reservior and waited for my wife to follow me to
the guy who was going to fix it. And for there to be less traffic, because I knew
I only had about 3 brake attempts and 8 miles and 2 stop lights.
Started out the driveway and found out about the siphon thing.
Lucky I was able to get back into the bottom of the yard and go uphill.
Refilled and bled, we pulled it off.
It was an auto. I hate driving with no brakes in an automatic!
Someone posted about E-brakes.
Who has an older vehicle with a working E-brake?
Inspection stations don't even check them.
If you do get them pulled on, they stick. One reason many cars wear out the front pads.
That's another thread.
