Old washers are off correct?

if so the mating surfaces are shot on the brake hose most likely.

Front brake issue

Yes, we used the new washers.

This must not be my day...
Somehow in some odd way the leak quit (for now at least).
But for the life of me I can't get the brakes to bleed (or at least I hope that this is my problem).
Here is what it is doing now...
With the car off, brakes feel fine. But start the car up and the pedal goes all the way to the floor with little stopping power. We have bled and bled with the same results. The reservoir is topped off.

Now what?  ???

It goes to the floor because with the car running it is now power assisted - or power brakes.
I am not sure how the leak would just "stop" leaking.
Just for a note - I blew the seals out of my newly rebuilt calipers I refered to earlier by bleeding them to hard.I know it sounds odd but it happened. Someone told me to bleed them out with the car running instead,and after I fixed the seals _again_ , I bled them with the car running and it worked !!
I am perplexed on your leak........maybe the flare or end that fits into the caliper is dinged up , or not seating correctly.If it was leaking out fluid, it could be sucking air in , and now airbound ??
Wish I was there !! lol - love tackleing the odd quirks.

The pressure differential valve has probably slid to one side and stopped the leak.
