Question on bleeding brake fluid
 

I need to bleed by brake fuild. I used to bleed brake fluid on many cars before, but not a P. On P, I know that brake fluid and clutch fluid are on the same system and refill the same resevor.

My question is that if I bleed brake, do I have to bleed clutch?
If I do, do they have to be in order? Which one to do first? Brake or clutch?
How much fluid should I buy? I don't want to stop in the middle of the process to run to the autopart store.
Thanks in advance.

Are the systems paired together? I'm not familiar with the G50.

You can bleed the Porsche brakes just like any other car. Start at the furthest wheel from the master cylinder and work your way around the car. Do you have any of the service manuals for your car? If not, spend the dough and at least get Wayne's book. These cars are just like most as far as the standard procedures. The Porsche books will help you with some of the more specialized repairs/upgrades. One quart should be enough to bleed the system. Check out some of the threads here for suggestions on using the blue vs gold, DOT 3 vs DOT 5, etc.
I am upgrading my entire brake system next month. I am still debating on SS hoses or not.
