Porsche Brembo 996 BBK Conversion-- let's figure out how to fix the dust boots/seals

[OPS]

Yeah I was banging my head for a while and just gave up to be honest. A former employee of Stoptech posted an inside view of what went wrong over there. It was insightful. Frenkit is full of motor heads which is exactly who I like to deal with on this hobby of ours. And they listen. Been working with them for almost 2 years now and it is a breath of fresh air.

Well, no dust boots on the AP calipers, so you definitely wouldn't need to worry about them then

I'd prefer to make this kit work, with giro discs and pads from fcpeuro. That lifetime is hard to beat. I need to see how hard it is to rebuild these dust boots. Jickel claims his gt3 dust boots have been gone a while and his braking is still fine.. tracks at Cota on his gt3 but has the AP kit on his e46 😂

Unfortunately I do not as Frenkit does not make their kits like that. The cost of changing packaging and part numbers make it a tough to be honest. You can check out their complete line by going to their website however! Frenkit.es. I will bring this up to them when I meet with them next.

Nice to see you guys get another seal than those grey stoptechs (perhaps it was a forced situation with the centric issues, but still).

Ah no worries. The entire kit is super affordable anyway, so I'll probably just buy it anyway and keep the seals as spares.

Yeah I don't expect these dust boots to last forever with the cooling scoops, but I'm happy knowing that they do extend the service life.

The OPS/Frenkit boots are next on my list to try. OPS do you sell just the dust boots? All I see on your website are kits comprised of boots + seals.

[OPS]

We are always here also should you need another choice for silicone boots and/or pistons. Frenkit performance just finished their trade show in Germany two weeks ago.

Demon Speed sells uprated boots
On these calipers in hard use environment expect 25-50hrs out of the dust shields max, its the rebuild cycle on my racecar with effectively this brake
The ceramic pucks help but fall out all the time and are a pain

glad I read this thread, before I invest more money into thi skit which ran perfectly fine at Sebring in HOT florida weatherr. I am scared to cehck the boots. I might just use this as an excuse to buy an AP KIT

Just another data point. Girodisc dust boots did not survive either

Swapped to a brand new set of Girodisc dust boots and installed the Bry5on scoops. Boots still look fine after a track day!

Same pads, same fluid, same track, same basically everything. Only real difference was the addition of the scoops. More analysis here: https://nam3forum.com/forums/forum/m...142#post279142

What street pads were you running?

Hawk ceramic. I am not crazy about them. At the time the car was my daily, and I bought them in the hope that they would be clean. They have not let me down on that.

This is the fist time I have noticed that the pads are a bit too tall and extend just a bit above the top edge of the rotors. They do fit nicely at the bottom. Is this to be expected?[/QUOTE]

Yes, once you get seriously moving and put enough heat in, the rings will expand radially and grind that off.

That said, at slower pace, you don't need to do anything with that edge, it will crumble away naturally, so you don't need to take anything out to clean.

First ever track day. It seems I was not terribly hard on the brakes as my plain-Jane Centric dust boots held up.

Centric made the parts for stoptech and in 95% of the applications I recommended them. You have tons of pad which in itself is a nice thermal barrier. I would take out the pads, clean them up, and put them back in. But overall I wouldn't loose any sleep over that!
