I had bad seals on the reservoir and replace them. Now I have to flush and bleed the system. After some research I found that it is recommended to bleed with a power bleeder instead of pumping the clutch and break petals. I understand how to use the power bleeder but don’t know what pressure settings to use. Has anyone used one of these devices? This is my 1st Porsche and I want to do everything right.

Thanks for the help

Lower pressure is better because it is less likely to entrap air. I use 5 or 10psi. I had to use 15+psi to push some crap out of my right rear caliper the first time I used the power bleeder.

Great tool. I've done it several times and find that 10-15 psi works well for me.

thanks for the quick reply. I do love the car and like even more doing most of my own work.

828 break? Is that like the 8:30 break but two minutes earlier?

I wondered if someone noticed I typed 828 instead of 928 guess next time I will check the posting before I click the post button. I was so surprised how many people love these cars. I am glad for the wealth of information and support for such a special vehicle.

Hey Leon,
Use the lowest pressure that gives you flow out the bleeders - it's not a pit stop race, so take your time: if you jack the pressure too high, there is a distinct risk of blowing off the infamous 'blue hose' hiding under the booster. Do that .... and you will become very intimate with your car .
IMHO, there is absolutely nothing wrong with the two person pump & bleed technique ..... but I finally did assemble a pressure bleeder, and find that 7-8 psi ( using a precision regulator off an air line) works very well.
