Performed my first ever brake fluid flush (on any car) yesterday. Very easy task using a pressure bleeder. I spent more time removing the wheels and getting the Cayman up on the 4 jack stands.
I purchased a Motive 0100 bleeder from Amazon, but returned it and purchased the Schawben bleeder from ECS Tuning. I liked the idea that the Schawben has a pressure relief valve, and a swiveling quick disconnect. It did not hurt that ECS Tuning was running a great sale on the bleeder.
I used the dry flush method, 9 PSI of pressure and everything went smoothly except for the spill.

I was filling the brake fluid reservoir when I had a spill. With the reservoir strainer in place, fluid goes in very slowly. Using a funnel I was watching for the reservoir to fill not realizing the funnel was overflowing.

. Fortunately, no fluid got on the paint, and I had clean cloths and a spray bottle filled with a water/soap solution to clean up any possible spills.
The Flush
There were very few bubbles and the fluid was not discolored. However, I saw small white flakes flowing through the tube as fluid exited the caliper. I observed these flakes at all 4 calipers. There wasn't a lot, but it was noticeable. The flakes were only present when I first opened the bleeder valves.
If you don't mind working on your car this is one of those tasks that leave you with a great sense of satisfaction. I rate the difficulty as 3 on a 10 scale.
