Hi, can you tell me how you are bleeding the system? Do you have a power bleeder?

Customer: replied 5 months ago.
no
Expert:  porscheguru replied 5 months ago.

Is someone in the car pumping the pedal?

Customer: replied 5 months ago.
Expert:  porscheguru replied 5 months ago.

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?

Customer: replied 5 months ago.
gravity bled them after turning rotors. good pedal . pedal bled them one time each side .front brakes. fluid level no longer dropping in tank.
Customer: replied 5 months ago.
someone pumping yes
Expert:  porscheguru replied 5 months ago.

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.

Customer: replied 5 months ago.
cant afford it
Customer: replied 5 months ago.
no air has entered system tank never dry. will no longer gravity bleed
Customer: replied 5 months ago.
should switch be on or off
Expert:  porscheguru replied 5 months ago.

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?

Expert:  porscheguru replied 5 months ago.

key does not have to be on

Customer: replied 5 months ago.
no pedal
Customer: replied 5 months ago.
fluid pumped out no air came out. level in tank never dropped
Customer: replied 5 months ago.
where is master cylinder located
Expert:  porscheguru replied 5 months ago.

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

Customer: replied 5 months ago.
can make one with fluid transfer pump and another cap
Expert:  porscheguru replied 5 months ago.

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.

Expert:  porscheguru replied 5 months ago.

That would work because somehow it got air in the system and the power bleeder will push it out.

Expert:  porscheguru replied 5 months ago.

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.

Customer: replied 5 months ago.
this one has hoses going to master cylinder from tank does not snap tnto cylinder
Expert:  porscheguru replied 5 months ago.

Let me look at something, one sec please

Customer: replied 5 months ago.
not valves took them out.
Expert:  porscheguru replied 5 months ago.

Where are you looking at the reservoir? Right in front of the driver area by the cowl in the engine compartment correct

Customer: replied 5 months ago.
says mineral hydrolic fluid only. G002000
Expert:  porscheguru replied 5 months ago.

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?

Customer: replied 5 months ago.
tank has 2 hoses one larger tha the other. not at vehicle
Customer: replied 5 months ago.
do not see booster under hood
Customer: replied 5 months ago.
do not see master cyl under hood
Expert:  porscheguru replied 5 months ago.

Can you send me a pic of where you are at? Thanks

Expert:  porscheguru replied 5 months ago.

I think you are at the power steering reservoir

Expert:  porscheguru replied 5 months ago.

Is this where you are at?

Customer: replied 5 months ago.
where master cylinder res?
Expert:  porscheguru replied 5 months ago.

Here you go, factory instructions. You need to remove the brake fluid from the PS reservoir and only use Pentosin or suitable substitute.

Expert:  porscheguru replied 5 months ago.

You will remove the small cover and there is the brake fluid reservoir

Expert:  porscheguru replied 5 months ago.

Are you good now?

Expert:  porscheguru replied 5 months ago.

Do good gravity bleed on all 4 calipers and all 8 bleeders to get all of the air out

Customer: replied 5 months ago.
bought fluid g002000 at porsch. 40$ did not use dot 4
Expert:  porscheguru replied 5 months ago.

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.

Expert:  porscheguru replied 5 months ago.

DOT 5 is synthetic and you do not want to use that.

Expert:  porscheguru replied 5 months ago.

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.

Expert:  porscheguru replied 5 months ago.
