By fades to the floor and don't recover. do you mean it stays on the the floor while running?
No it just goes to the floor when applied and engine running and returns to the top of stroke.
So this weekend I blocked off the master cylinder, with dummy fittings. Problem went away had solid pedal eng running or not.
So I went to HF and got a vacuum bleeder. Bleed the entire system probably 10 times. Still had a mush pedal that went to floor with engine running.
So pissed I took a break and then bleed it once more. Ready to give up I decided to at least move the car and get ready to take it to the scrap yard lol.
As I was moving it around the pedal kept getting better. So I took it for a test drive....
I'm not sure if there was just a tad of air in there. But it's fixed, or at least back to normal. I mean it's a 94 Sundance it never had a beautiful pedal it great stopping distance
