Porsche Repair Questions? Ask a Mechanic for Answers ASAP
Hi, can you tell me how you are bleeding the system? Do you have a power bleeder?
Is someone in the car pumping the pedal?
Please do not think I am being disrespectful if any of my questions seem remedial but I have to start somewhere to know where you ae at. So you have another person in the vehicle and they pump the pedal and hold it and you open the bleeder on which wheel and inside or outside bleeder?
Would you be willing to talk on the phone? It is a much easier process for a small cost. I want to get to the bottom of this for you.
No worries. So you gravity bled and the fluid was flowing well in the reservoir via gravity bleeding. Then you pedal bled them one time and it was good. But you tried to pedal bleed a little more and then nothing? How does the pedal feel now?
key does not have to be on
Pedal goes to the floor now?
Do you have any type of power bleeder available?
I always bleed with a power bleeder and have never experienced this and I only work on Porsche.
It can be a cheap power bleeder, even a mighty vac one would help
It is right below the reservoir. The reservoir actually snaps into the master cyl. through the fill holes on the bottom. I would not condemn the master yet. I do not see them go bad.
That would work because somehow it got air in the system and the power bleeder will push it out.
Also I have seen the caliper bleed valves act a little weird where you think they are tight and they are not. Another thing, sometimes the bleeder get nasty and you have to pyull them completely out and use a small piece of wire to make sure they can allow fluod to go through.
Let me look at something, one sec please
Where are you looking at the reservoir? Right in front of the driver area by the cowl in the engine compartment correct
This is the parts catalog image but I am not sure what you mean by lines. Do you think you could take a picture for me?
Can you send me a pic of where you are at? Thanks
I think you are at the power steering reservoir
Is this where you are at?
Here you go, factory instructions. You need to remove the brake fluid from the PS reservoir and only use Pentosin or suitable substitute.
You will remove the small cover and there is the brake fluid reservoir
Are you good now?
Do good gravity bleed on all 4 calipers and all 8 bleeders to get all of the air out
Porsche factory fluid is DOT 4. You don't have to buy Porsche fluid. ATE type 200 is the same thing as ATE super blue but it's amber. It's the law now that all brake fluids must be amber.
DOT 5 is synthetic and you do not want to use that.
If you are good now, I am going to say good bye and I am glad we were able to get you in the right direction.
