(should only be a very short period of time). Then repeat the same with all four calipers and for good measure with the clutch bleeder under the car on the drivers side, see bentley for a good pic.
PS If you don't have a power bleeder have an assistant pump up the brakes and maintain pressure on the pedal when you open the bleed screws. Do each wheel, two bleeders per wheel one at a time, if that doesn't fix it then I'm with lil B prolly a master cylinder.

So I bled the brakes, and the problem disappeared for about 10 minutes. It then returned; I jacked the front end up, and checked the wheels while a buddy braked. It looks like the passenger side front is spraying a small amount of brake fluid out when braking from behind the caliper at the attachment point of the brake line and the caliper.
Thoughts?

it looks like you have been working on this car for 8 mos. perhaps a flatbed to a repair shop would speed the process along.

Well, it's not a huge problem. I have 3 cars, but I drive the Porsche 2-4x per week. I've put 30k on it in the past year, and the little irksome things are starting to pile up...

not squirting, and it's been about 10k like this. It's merely fizzing some aerated dribble. not enough to even lower the MC readings at all.

the brake line maybe held on by a 'banjo bolt' it can have 2 crush washers that are supposed to be used once. they can be leaking or the bolt can be loose. the line where it swagged can be old and leaking. i dont know what year it appeared in but does this car have "hill assist" ? on the dragging brakes : fix leak first then jack up each wheel ...apply brake then release...look /feel for one wheel dragging...if so maybe stuck caliper/stuck pad/ crushed [inside] brake hose...if all 4 wheels drag...back track system.....if just fronts drag...back track..if just rears

it's def. one wheel dragging (front passenger) and it's a 99, no options. I think the seal from the line to the caliper is bad.... any thoughts?
