Default spongy brakes until third pump problem.

so i bought some ss brake lines and installed them last week and never had to bleed the brakes myself until then. ive tried the two person method, gravity, and with a mighty vac bleeder but still spongy brakes almost to the floor while driving until about the third pump. anybody else had this same problem before? i dont see any air comin out anymore when i bleed.

maybe the master went dry as you where replacing the lines? try bleeding all four wheels starting RR RL FR FL in this order add fluid as you go. is fluid coming out strong when you bleed them?

Be extra sure there is no seepage at line connections. Especially the flared connection. Seen this 1x time before with a brand new line. It was defective.

I hope your master isn't leaking into the booster, this is rare with these cars but can cause those symptoms.

What happens if you pump the brakes, then keep pressure on the pedal? Does the pedal start to go down to the floor? If so... maybe a leaky seal in the master.
