Don't let Joe fool you he was a professional for 45 years.
He knows more then all of us put together.
At the same time he has lots of time pulling our chain.
Now lets see, he is in to bikes, cars, naked women and playing possum / dead.
The order may not be accurate.
S*T I better watch out, I got a guy pissed off not to long.
No, he was a party pooper.
But I do hope I helped fix his car.
Joe read on bleeding brakes, there is a special procedure for your car
I think you have a valve by the master cylinder to play with.
And don't forget to open the bleed screws when you back the calipers.
If you can get the ATE fluid go for it it may be better.
Although I am no so sure.
Hydraulics are not compressible, so there should be no difference in pedal feel,
now if you get them hot is a different story.
Maybe you had air or dirt in?
You should flush the fluid out every year any ways.
Every time I have the car up I vacuum the brakes a bit, to be on the safe side.
But the difference on dot 3 or 4 is the boiling point.
And maybe rust inhibitors, not so sure about that either.
The reservoir has two compartments the one in the far side you can drain it with out knowing it, and put air in the system.
Make sure you got the oil up on both, there is a small hole that connects them,so when you look at the left and you add the oil it takes time to go to the one on the right, so you are pumping air in...............
Remember small holes are difficult to.......... Fill up.
