I read on this forum (and elsewhere) that when flushing the braking system of the Cayman (987.1), one should bleed both valves in each of the four calipers, starting with the outer one, followed by the inner one. Is it necessary to do both? Or, put another way, what happens if only the outer valves of each caliper are bled?
You don't flush the old fluid from the inner pistons of the inside half of the caliper.
If you add a tee or wye fitting into the bleed hose, you can bleed both sides of the caliper simultaneously.

I'm a little confused by these two responses (Greywolf and Croc'ed). Is there a contradiction here, or are you both saying that it's optional to bleed both valves, though one can just do the outer valve on each caliper and be done.
I think we're both saying the same thing. Do both sides. Individually or at the same time.
Apologies to Croc'ed if I've misspoke for him.
Bleed both sides.

And the clutch if you have a manual. It shares the same reservoir.
Thanks for your responses, Grewolf, Croc'ed, and Zuch. I will definitely bleed both caliper valves (and the clutch) next year. BUT ... my real reason for posting this question is this: I had my local dealer bleed the brakes and they definitely bled only the outer valves. The rubber caps of the inner valves are undisturbed and completely dry (unlike the outers). I must say, I'm mighty unimpressed. (I just hope they properly bled the clutch!)
Unless they specifically charged you for the clutch flush, I wouldn't assume it. Especially since they muffed the brake flush.
There was a separate charge for the clutch work. Had to remind them a number of times to do this. Seems that it's not a commonly requested item!
I'm beginning to lose faith (again) in dealerships. Getting a "ballpark quote" of $1000 for flushing the power steering fluid was quite surprising/odd. And then there's the odd argument I had with my (then current--I've since switched) indie shop over whether to use distilled water when flushing the coolant (they use only tap water, and our water is mineral laden).
Bottom line I guess is: if you want done right (or just different from the norm), then, do it yourself.
