Part number or source for these brake caliper bolts please

[TAV]

HI

I'm looking for these bolts circled in the picture below. The pic is for example only.
The calipers I have are rear 993 calipers, and I have 2 missing unfortunately.

Any help with part numbers or source would be greatly appreciated

Thanks

You're not going to find a part number for those bridge bolts because the factory manual says that the calipers should never be split. It's a load of crap in my opinion because splitting the calipers is not a big deal. I mean, the older 930 calipers were clearly a more intricate assembly and that caliper is shown exploded in the parts diagrams. I'm guessing at some point there came a worry of liability in disassembling the calipers and that's why you see only a whole caliper, aside from the piston + seals assembly and a few other miscellaneous parts, shown in the parts diagrams.

That said, i've taken apart some of these later Brembo calipers. The bridge bolts are basic 8.8 class socket head bolts and I bought them in bulk from Metric & Multistandard Component Corp. The only problem is that they're not plated, they're a black oxide coating. So i'd recommend having them plated. Reason being is that the steel bolt and aluminum caliper body have a dissimilar metal condition that fosters corrosion. You'll see when you remove the bridge bolts that the entire shank of the bolt, even when its plated, is coated with copper anti-seize paste.

Also, be aware that removing these bolts can be a real battle. Heat is your friend and so is a fluted extractor bit (cut to size to bite into the bolt's hex tooling) when the hex bit you're using strips the head of the bolt.

Let me know where you're located and I can ship you a couple of those bolts. I have both sizes in the proper length. They are different sizes- M10 and M12

Thanks kevin! That’s super helpful. I have located some bolts.
Also thanks for your cad drawings in the past re: fitting 993 calipers to a 911sc

Cheers
