I have a new-to-me 2009 base Carrera, 35k miles. I have noticed that all the heads of the pad guide pins (good picture in post #7) have some corrosion and need to be replaced. The heads look to be triple square, not Torx. Can anybody help with a part number? Are there four on each caliper? I've not been able to find it online or in the Porsche parts catalog I've downloaded.

Yes, that link is for same document I searched. I don't see even the same calipers that are on my car. They are not "open" like other Porsche calipers, so caliper removal is required to change pads. What I'm looking for appears to be pad guide pins that screw in from the outside of caliper. Good picture of this part in post #7. It looks to be a common part, but I didn't think it'd be so hard to find.
This is picture of the bolts I'm talking about. They appear to be brake pad guide pins as there are four per caliper, two inboard and two outboard. The heads are either triple square M12 or M14. I've got a set of male triple square socket bits but am having heck of time finding the matching internal sockets. Hoping it's not a specific Porsche tool required.

There is no practical reason to remove those studs. If you are concerned about the cosmetic rust on them, why not just wire brush them, mask and paint?
You're probably right. I'm disappointed though that a common fastener like this isn't available. Fellow at Suncoast told me I'd have to buy new calipers to get those fasteners, which is out of the question. I've got some time as car doesn't need brake job now; this is my first Porsche, so am learning the car after a string of nine BMWs. I was able to solve the tool problem should I need it though. Sears p/n 92496 is a 9-pc set of metric universal sockets that work on several types of fasteners including this one. Doubt they sell the one socket needed so added the set to my kit for $17.
I have the same issue on my 09 C2. The ends are all corroded - much worse than yours. I’m going to pull them out, wire brush them and paint them when the nice weather returns.
Reviewed the 180 page Service Information (2009 Technik Introduction - All 911 Carrera Models) book that came from PO. On page 117 there's this: "The brake system for the new 911 models with 3.6 liter engine has been completely redesigned. Apart from the larger brake discs on the front and rear axle as well as additional active ventilation of the the brakes on the rear axle, the main feature of the new generation of brakes are the completely redesigned calipers on the front axle."
Swingwing, would you mind posting a better picture of that socket including the size? I went through my socket sets, thought I had one that would fit but unfortunately no.
Also unfortunately Sears went bankrupt in Canada a few months ago so no longer have access to Craftsmen tools.
Thanks, Scott
No, the caliper bolts (two each hold the caliper to the hub knuckle) have not changed. The fasteners we're talking about are guide pins for the pads. There are four of them on each caliper. See the pictures in posts #7 and #19. I have found a socket that fits the head but unfortunately Porsche doesn't offer replacements on this part.
I have a 2009 Carrera and want to DIY on rotors and new pads. Have reviewed threads and watched all videos regarding replacement. I can't find anything on my model type. Carrera model has a totally different caliper than an S model. It's different from 997.1 also... Anyone done this that can detail how to get to pads and replace?? Also, can I exchange Hawk Ceramic pads for OEM.. There seems to be a special shim... Thanks!
While the Hawk Ceramic pads have the least amount of brake dusts compared to OEM, but braking it when it is cold and on public road is not as effective as OEM. After warming up they are effective, but who warms up their brakes while driving on the street ? I use Centric pads and they have minimal brake dusts and extremely effective on the street even when the brakes are cold. The Hawk ceramics are supposed to be suitable for both street driving and occasional track use, but unfortunately my experience is that they fall short on both. I'm happy with the Centric pads and if I want to track my Pcar, I change it to track pads.
You'll need to push the brake pistons back slightly so the pads will clear the lip on rotor edge. You should be able to do this with a screwdriver or similar tool.
