I just got done bleeding the brakes and clutch slave cylinder. And I am pretty sure that I got all the air bubbles out of the lines. But my brake pedal isn't as firm as I remember it being before I did all the work. If I recall correctly there wasn't really any movement in the pedal before the brakes engaged. Now there is a half inch to maybe an inch of movement before it gets firm and the brakes actually apply.

Is that that much movement normal on 944s? Also it is fine feels nice and firm when the car is off, but as soon as I turn the car on the pedal moves in.

Mine will travel maybe a half inch before the brakes start squeezing; you might have had too much fluid in before, hence the higher pressure. As for the pedal movement of on/off, that's just the vacuum brake assist.

Well I drove it for the first time today and the brake squish is a lot worse then I thought. It feels like the brake pedal on my surburban. And now my clutch engages really close to the floor and some times doesn't come all the way up. Is it possible that I still have air in the lines?!? How long should I let the fluid run clean when i am bleeding the brakes? I let it go for a good 20 seconds or so without seeing any bubbles.

Did you also bleed at the calipers, and not just the master/slave cylinders?

You also want to bleed in a certain order - RR, LR, RF, LF

Did you use a pressure bleeder? When I do it, I let it run for quite a while -- but also do a flush at the same time, so I want to cycle the old fluid out.

You could also tap on each caliper with a hammer while the bleeder is opened and the fluid is flowing out -- this might help shake off any air bubbles that are stuck on the inside.

Good luck!
