My front caliper components are fried - some of the yellow pucks are shattered / all the rubbers gone (nice work PO on your preventative maintenance program).

Is there a difference between the various GT 997 calipers (gt3 / rs / cup?)

These ones have ceramic yellow pucks.

Cheapest place to source these parts?

Also is there a genius want to plug the brake lines when you take the calipers off the car to rebuild them?

As far as plugging the open lines, this is what I use:

New tool to me! Ordering now

U can get the correct female flare fitting as an adaptor to npt and just get a npt plug. That way i wont run the risk of damaging the core in the soft lines.

Those yellow ceramic pucks are no longer available. I think Demonspeed sells replacements but they're not the same as OEM.

Meaning they arent as good or dont fit?

What are all the 997 cup guys doing?

I can't comment on fitment or quality. I've luckily never had to use them. Just telling you that you can't buy the OEM pucks anymore and Demonspeed is the only other option, unless you buy brand new calipers.

This is the best solution. I got these from the UK, then put a small piece of rubber down in the bottom. They are somewhat expensive for what they are, but they work awesome and fit pretty much all Porsches.

I bought them several years ago, at the time this was the only such part I could find. Maybe they are available stateside somewhere now (McMaster, Fastenal, Grainger, etc). Not sure.

I’ve used the Demon Speed pucks with great success. As Doc says, the OEM are NLA at this point. The piston diameter changes on 996/997/cup/etc so measure them before ordering.

I wrote up the rebuild I did (almost a decade ago...) HERE.

If you already bought the cool German clamps, have fun! If not, as shown, since the brake system is not pressurized (as long as your kids do not jump in and press on the pedal...), you can cap the line with any number of flexible "nib" caps. I used ones that they have for covering the sharp ends of the wire shelving sold at home improvement places.

I also have used a finger cut off a nitrile work glove and a rubber band, works fine...

LOL - I found that post in my searching.

Why I love this forum - its the last remaining one like this - all the rest is on facebook and impossible to find info

Demonspeed sells all the stuff needed

got them all rebuilt - their pucks are aluminum vs ceramic, but seem fine

Their new seals look to be more high temp resistant, but the pucks are totally stuck in the calipers and will fall out of the seal if you arent careful

Friendly and good service - good choice
