Hi all, I have been searching for affordable rebuild parts for factory 4 pot brembo 968 calipers. Anyone got some ideas on the best place to get them?

Cheers

"Affordable" and "Brembo" are not words that go together. Expect to pay $400-500 just in parts to rebuild all four calipers.

If you find a cheap or alternatove source for the parts let us know. GL

Racers Edge can also provide the dust seals and rings at competitive prices.

You shouldn't need to replace the pistons, but definitely replace the inner pressure seals and the dust boots. Even with Brembo branded parts it will not be THAT expensive. Paragon has parts as well as some other places also. You can use the Stoptech parts also. I used those on lots of caliper rebuilds as they were more readily available and about 50% of the Brembo price at the time (some years back) but I never had an issue with any of the caliper rebuilds using the Stoptech parts.

Thanks for sharing. At $35 for two pistons that's $280 for the whole car, cheapest I've seen, not too bad as long as the pistons are good. Good time to also replace the bleed screws and backing plates WYIT.

Hi all, I order have my kits and started to remove one of the 40mm pot on the front caliper, I dont seem to be fully able to remove the dust boot, it seems to be stuck under the Stainless Steel shim, is this the same on other calipers? Do you need to remove the shim to replace the dustboot?

Cheers

Rob

If i were you i would take apart the entire caliper, all of the bolts out and replace them as well. The bolts are only 20$ in total so that's not a big deal. It makes it a lot easier to work on and than you can also get them sandblasted and painted!

And yes you are correct, as long as the shims are in there you will not be able to remove the dust boot!

I think what youa re referring to are the metal plates that are at the ends of the pad opening. These are actually called "Spring Plates" (Don't ask me why Porsche/Brembo calls them this- I dunno) You will need to remove the spring plates to remove the dust boots. This means you will need a torch, like a Oxy/Polypropelene (standard propane torch will not get the button head screws hot enough) You need to heat the head of the allen/hex button head screw til they just barely glow orange for a moment or two after removing the heat source. Then insert your hex/allen wrench into the button head screw (it's an M4 if I recall correctly) and crack it lose. Be careful here as what you don't want to do is to strip the hex of the button head screw as then you have a real mess...

Once you have it "cracked" lose it's pretty easy to back it out the rest of the way. You will need to replace the button head screws. You can find them at Metric & Multistandard or McMasterCarr. They are an M10 x 10 (again if I recall correctly)

Somewhere I have a video of this procedure. If I can find it later today I will post/link to it for you.

I would also suggest picking up a tube of Dow Corning #111 Silicone lube. this is what I always used to lube the pressure seals before putting them in. Many will use brake fluid to lube the seals but I liked the #111. It worked well for me over countless caliper rebuilds.

If you need/want more help PM and I will send you my phone #.

Stoptech sells individual seals and square rings. Can't remember the 968 piston sizes offhand but they will have them.

If you buy the 968 brake repair kits from Sonnen Porsche, you'll be out about $375/shipped for factory Porsche parts. Includes dust boot, piston and inner seal. Heck of a good deal if you ask me.

The Hex bolts are M6x12, just replaced them 2 months ago!

Also did the allen bolts which hold the caliper together, those are m10x85 and m12x85 if i remember correctly but that could be wrong..
