Brake Replacement Question - Dampers
I'm getting ready to replace my brakes (pads/rotors) and have done a bit of research but still have a question. Do the brake dampers need to be replaced and if they are reused do they reattach to the new brake pad or do you remove the pad and the damper remains in the caliper? Not sure where the adhesive part of the damper comes into play. I thought I saw some pictures on this but could not find it again last night bouncing among the various forums. TIA

When you pull the pads out of the caliper you may need to separate the damper from the pad with a putty knife. They tend to be stuck on very tightly with anti-squeel adhesive. Once separated they can be removed from the caliper after the pad. Again, you might need a putty knife to unseat them from the caliper piston. They just pop out.
If the dampers look to be in one piece and in good shape reuse them.
When you put new pads in put the dampers in the caliper first. Get them seated in the piston holes. Spray the back of the pads with anti-squeel adhesive, let it dry, then slip the pads in. (Clean up the damper with brake cleaner first so the adhesive will stick)
Very easy to do a second time. You'll wonder if you're doing it right the first time. Make sure you note that the piston holes in the caliper are different sizes. Remember how the dampers went in so you don't fumble around.
The whole process is quite easy. You'll just doubt yourself the first time. Good luck.

On this note, does anyone know if classes exist for the DIY lover without going too much in details? My goal is to manage brakes, oil, basic liquids and equipment and not be a full blown mechanic....

The 997 brake pad swap is virtually identical to the 996 brake pad swap.

Sorry for the bump... can someone confirm the sizes required to replace all brake pad dampers on regular 997.1 C2S brakes?
4x 99635108901 for the fronts: https://www.ecstuning.com/b-genuine-...h/99635108901/
2x 99635208600 for the rears (30mm) https://www.ecstuning.com/b-genuine-...h/99635208600/
2x 99635208602 for the rears (28mm) https://www.ecstuning.com/b-genuine-...h/99635208602/
Is this correct?
Edit: Found this thread with my same part #s, but don't see a 100% confirmation in there:

According to PET those numbers are correct for a 997.1 C2S without ceramic brake rotors. But you need 4x 30mm dampers and 4x 28mm dampers on the rear axle (8 pistons total on the rear axle).
The part numbers are different if you have the ceramic brakes option code I450.

Heres a trick to save money !
If you examine the Porsche brake pad dampeners, they come on circular steel plates with an adhesive pad. In fact, the adhesive pads are from 3M and its called 467MP. Do a search on Amazon and you'll find it. It comes in rolls or sheet form and they are very reasonably priced. These 3M adhesive pads are very thin and won't impede braking performance and it also won't impede brake feel. Don't use any other adhesive pads. The origin Porsches pad dampeners have these sticky sheets on them. Just reuse the existing dampeners, but sand off the old adhesive gums and reattach new 3M pads cut to size.

Chiming in...
Regarding the below. This is good advice. I just completed a brake job on my 1995 993 C2. Rotors and pads all around. Replaced the wear sensors too. Everything is easier when you take the caliper off. I had to since I was replacing rotors. I did not mess with any brake lines. Just hung the caliper with wire from the spring on the suspension.
for the dampers, I put the pad in my bench vise. Took a pocket knife and hammer and gently got the knife under the damper enough to get a std screwdriver in there. Gently pried around them to get it off. All 16 I was able to reuse this way.
good tip to spray back of new pad with crc anti sqeal spray.
also, I inserted dampers back in before reattaching caliper then once attached, slid the new lads back in
all in all, a pretty easy job. Just take your time.
