Porsche Brembo 996 BBK conversion

In my experience, the stoptech (centric owned) seals are slightly looser than OE brembo, so their pistons also being slightly larger should be fine. You're also talking about hundredths of a millimeter.

A trick I tried once was when I had one seal feel too tight, I moved it over to a bore where the fit was a little too loose, then moved that looser seal back over to the first bore where things were too tight. Both then were snug.

I would highly suggest using proper install lube rather than brake fluid - it provides much more lubricity and makes it easier to push the pistons past the new seals. If you bought the new seals off ebay (Ohiomotorsports), then it comes with proper lube.

Hi, I just received the new centric pistons for the rebuild of my rear 996 brembos and I wanted to share a few images I took to compare them. I took some measurements and they are pretty close, the new pistons are 0.02mm bigger, I wonder if this is just down to tear and wear. I used centric as I could not find original brembos in the US, plus the centric items are cost-effective. Does anyone have experience with these? I hope they are of good quality. I also used their seals.

BTW; I don't track the car, it is just my weekend toy and I cannot say I drive it aggresively as the public roads here are very busy and there are very few B-roads.

and the front 2.7L front pads for the rear 996 Brembo's

I don't see how they'd work (dampen vibrations), if they're not fixed to the pads. The pads are already mostly immobilized by the pins and the spring clip on top. What keeps the pad then from vibrating or moving that little bit that creates noise? I assume it's these dampers stuck to the pad and stuck inside the pistons.

Word of advice- the temptation to adhere these dampers to the pad before install is strong, but it will screw you up unless you guess perfectly. It's best to stick the dampers into the pistons, then peel the backing, and stick the pad to them, as the pad is resting on the pins.

I didn't reuse the dampers.

anyone using the front dampers? do you leave them as they are for easier reuse or do you adhere them to the brake pads?

and by the way my rear pads (front porsche) from ate arrived with a pin that i had to remove.
