I've booked my self a trackday in July and the last time I had a go on a track in a porsche I boiled the fluid (a 1987 3.2 not the 993).Apparently it was the moisture thats absorbed in the fluid that boils and should therefore be changed after 2 years. As I've no idea if this has been done I fancy doing it before July as having no middle pedel when coming to Chris's curves at Cadwell certainly concentrates the lower intestine!!!!!!!!
Whats the best way to change the brake fluid

You have the same callipers as my 944 Turbo and it's very easy to do.
First of all buy yourself an Easibleed kit from Halfords or similar (under a tenner I think). This allows you to do the job singlehanded and very quickly without getting any air in the system. You fill the Easibleed with new fluid, connect to a tyre and then to the brake reservoir.
Then its simply a case of opening each bleed nipple in turn (two on each calliper) with a 10mm ring spanner and the tyre pressure forces the new fluid into the system and the old fluid out of a pipe connected to your nipple (ooer [
]). I recommend ATE Super Blue as it is a good fluid, reasonably priced and is blue so you can tell when the new fluid comes through the calliper. They also do it in Gold for the next year.
Will take you around an hour first time, less in subsequent years. I change my fluid every Spring, and bleed a little out after a few trackdays.

be careful with the easy bleed,, I have this and have used it on many other cars, but when I tried to use it on the 3.2 carrera that I used to have, the fluid ended up all over the garage floor,, there is a little overflow pipe that simply, bleeds offthe pressure you use to pressurize the master cylinder,,
I recently had all calipers of my 993, for painting and, reflushed the system,,,, all you need is a decent clear hose, that you can see the bubbles in, and at least 1 litre of brake fluid,, I have used srf, but expensive, now use the ate blue and it seems fine on track,,,,,
if your changing to the blue stuff, it helps,, as the colour is different,, so you know exactly when the new stuff is coming through,,
you start at the cylinder furthest from the master cylinder, and work to the closest,, so nomally,, near side rear, off side rear, near side front, off side front....

Hi Maurice
My '96 C4 brakes need bleeding. Is the p-car solution (http://p-car.com/diy/flush.html) still applicable to a C4? Do you have any more information on the brake differences between the C4 and C2. I assume active brake differential comes in to it somewhere?[]
Many thanks
