$15(for a liter of super blue) plus an hour of DIY. Some wheels like the Carrera Classics are open enough you don't need to remove them to get to the bleed nipples.

USMC_DS1,
Do you notice any reservoir staining with the super blue? Considering this option, but I am following the 2year manufacturer recommendation. On all my other cars I use a measured amount if the fluid is the same color.
Thanks
Mark

Mark,
Not sure about the staining as I've only done two bleeds over the past 1.25 yrs on my '08 C2S. 1st bleed was over a year ago(after purchase) with the Porsche gold fluid. Recently I switched to ATE Super Blue. I've used the measured approached as well when using the same color fluid. That's a good method. I like to bleed again after a week of driving as well. Always surprising what comes out during the second cycle and that tends to work out the old stuff left in the ABS if you do some hard stops. Worked well before I got the Durametric tool which does have the ability to flush the ABS. I'm the second owner of my p-car and it looks like the 1st owner had never bled the brakes according to the dealer's maintenance records. So my 1st flush was near it's 3 yr mark. One thing I like about gold... you can see the old dirty fluid(a dark yellow) as compared to the new clear gold fluid coming out as you bleed it. Of course, blue vs. gold is even more telling in contrast.

Many get a little carried away with brake fluid changes. How you use your brakes is a big determinant of your interval period. If you're a weekend racer then you should do it more often. If you're just a street driver every 24 months is more than enough.
I understand the clutch bleed for the 997.2 cars is radically different than the 997.1 cars.

OMG, I'm going to watch their time very carefully. They've always been very good to me and I thought their prices were reasonable when compared to my Merc and the other indy shops I've used in the past. BTW, I purchased 2 liters of Super Blue and willbring it to them. I don't want to pay inflated handling charges.

I assume your Indy knows this but there are two bleed nipples per caliper on your car - outside and inside. And, of course, they should start the bleed at the farthest caliper/outside nipple and work towards the driver side front caliper last... so Rear Right(RR), RL, FR, then FL. Also have them inspect and replace if necessary your brake lines. Safest thing to do re use of proper brake fluid is just buy it upfront for them and ask for the empty containers back as proof. Some non-Porsche Indy's have a propensity to use whatever they have on hand vs. taking the time to order/purchase what is recommended by Porsche. So give them two liters of the Porsche brake fluid and ask that they us it all just to make sure the system is completely flushed(note that 1 liter is ok with skill).

jhbrennan, Yes, I've used the Durametric tool for the ABS bleed once... more out of curiosity than anything else. Not really convinced that it is necessary to do this though. BTW, Still remember your gracious action last year with the new battery. Very willing to help if you need for example to barrow my Durametric or to assist you with a basic bleed.

Well, I gues I just got ripped. I brought 2 liters of Super Blue to my indy ($45). They came back to me about an hour later and said they added 2 more liters because the old fluid was coming out white(air ?) and they used my fluid to flush the system. They then added 2 liters of their own. I asked them if they used Super Blue, they said yes, but I didn't see what they added. How can I tell? Total was $258.00 not including the $45 I spent on Super Blue. Lesson learned, don't take a P-car to an MB indy, you don't want to pay for their OJT!
