Hi All,
Now that the snow's receeded, I've brought the Cayman out for its first run, its brake discs are pretty rusty after being sat in the garage for a month, not to mention feeling a bit off colour. After a couple of short runs, the rust still hasn't come off the discs. Any recommendations on a braking to wear the rust off??
I figuring some fairly high speed braking to build up lots of friction and heat should do the trick.
Any recommendations welcome

My dad's indy recommends a run up to 100mph, then firmly on the brakes until a complete stand still is achieved.
Lather, rinse, repeat three times, and all rust should be gone.
Also, he said don't softly press the brake pedal: they are sports cars, and you should always try to make sure the brake pedal isn't used too lightly/softly. Always depress it firmly...

Have you tried driving the car (short distance!) right foot on accelerator, left foot on brake. This might generate enough friction to clear the discs of rust?
Just no. 
Bad idea, puts a hella' strain on so many components, it just isn't worth it.

The only true solution to this is to get the brakes hot before you put it into the garage. That ways you won't get any rust.
Unless you have a very damp garage?

What if I've already got 9 points....I don't want another 9! Lather, rinse, repeat three times, and all rust should be gone.
Back O/T I took my Cayman out this weekend for the first time this year and the rust on the discs was terrible, to the point where the hand-break was seized on the rear. I know I could leave it in gear with the handbreak off, but if I didn't expect for it to be sat unused for so long.
I've never experienced anything like it on any of my other cars which have sat about for much longer periods of time! FWIW mine lives out in the cold, so probably gathers a fair bit more rust that some, but as I said this has never been a problem in the past! I seem to remember this being a particular problem for the Boxster that was run by Evo as a long-termer a few years ago, so I guess it's a problem all Porsche's suffer with?
Thanks chaps.
I like the long twisty drive option, my car never really feels awake till its covered about 10 miles anyway! Or is that the driver! Anyhow, I'll give it a blast this weekend.
Must be said, the car had to go into the garage with snow on it, and it was pretty damp too, which I cringed at, but who thought it'd be in there for a month! Grrr. Looking forward to the spring!
p.s. I'm glad nobody has said, "aaaaah, that'll be new discs then..."

My 996 will allow brake and gas simultaneously... I usually give mine a run up and down the street with my left foot fairly firmly on the brake to dry the discs off after I've washed it.SS7

I just picked up on this thread - have same problem with my Boxster, took cover off last week and discs rusty, stripped them down and cleaned off as best I could but they will not come realy clean. Also can feel them fluttering under braking; tried all the ideas on this post but no real success
Anyone recommend getting them face ground - if so would appreciate names of good garages in Cheshire

You can get the brake discs reground on the car. It's a Porsche approved procedure. OPCs will have the equipment as will a lot of Indys.
With regard to the advice above, try 5 to 6 very hard successive stops from 60mph. Brake as hard as possible without inducing the ABS. Sorts out 90% of rust and associated vibration problems.
