DIY 997.2 Brake Fluid Flush
Compliments of cerbomark @ http://www.6speedonline.com

You need jacks to get the wheels off, 11MM wrench, bleeder pump (optional), Turkey baster, hose/container to collect fluid pumping out, Dot 4 brake fluid.(I used Synth, Valvoline)
First, use the baster to take old fluid down to the MIN mark only !!
Re fill with fresh fluid. Connect to power bleeder and pump (5-7 lbs is pleanty)... Note, I only used the power bleeder for the pressure and had to keep re filling the reservoir. Don t let it go past MIN.. or you can put fresh fluid in power bleeder and it will keep the reservoir full.
Each brake caliper had two 11MM nipple nuts on the top. Start with the rear right inside nut. Open and have hose connected to collect fluid. Do not turn the nut too many times or it may come out. Fill the small container and tighten nut. Do not over tighten. Then do outside nut and move to the other rear wheel and repeat. Always check power bleeder and reservoir to avoid running out of fluid. You do not want air inside the system.
Front V (Below)
Rear V (Below)
Then repeat front passengers side (inner and outer nuts)
Then same on drivers side.
Top off reservior.
Notes/ always use sealed bottles of brake fluid. Open containers are subject to moisture.
I cleaned wheels while off and left the calipers under pressure after bleeding to ensure no leaks.
If its your first time I can not stress enough not to let the system go below the MIN mark during this procedure.
997.2 s do not have a nipple on the clutch to bleed that like the 997.1 s do. There is a fitting that the dealer may be able to do that with but probably not important if you keep the fluid clean from the start. The dealer can also bleed another part of the system which requires special Porsche electronics. Again, I m not going to woory about that if I keep the fluid healthy. This cost me about $8.00 instead of several hundred. You be the judge, it s your car.
Anything I missed or mis informed about anyone can feel free to correct.
