Sorry, I know this subject has been covered ad nauseum. I want to do a hydraulic flush this weekend. I've never done the boxster. It was last done 2/07 by the dealer I bought it from. I have a nice brake bleeder machine left over from my bimmer days that fits the boxster cap perfectly. My question is: I'm in a small town and we have the basic stores, autozone, oreillys etc. What fluid would you guys recommend that I could purchase at one of these stores??? And also, how much should I buy to do all four wheels and the clutch slave??

thanks in advance!!

I think Porsche requires dot-4. ATE appears to be everyone's favorite for it's high boiling point. I actually found it at the best price at a local Honda dealer last year.

Thanks for the replies. I'm 90 miles from the nearest P-dealer. We do have a honda dealer though. I'm thinking of going with the blue stuff, as there is gold in there now. tnoice, do you think 2 ltrs is enough??

thanks

If you're experienced flushing brake fluid on the BMW then 2 liters should be enough. The first time I went a little overboard looking for bubbles and used every last drop of 3 liters. Changing fluid colors will certainly help you tell when enough is enough.

Yeah, the boxster looks pretty easy. I may not even have to remove the front wheels to get to the bleeder valves. The only thing bothering me is the clutch slave. It looks to be a nightmare to get to. I have to have someone or something holding the clutch pedal all the way in when I bleed/flush it too, right???

... especially if you're changing colors.
As soon as blue liquid starts coming out, that point is done.
You should be able to do all 4 corners (2 nipples per caliper) and the clutch with one litre.
Here are my instructions.
