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

[OPS]

I personally have never seen a piston seal fail. Failure will occur when the installation was incorrect (twisted or not seated correctly) or extreme lack of maintenance on the brake fluid. Met with Frenkit at PRI this last week and said I need the kits asap. They should be in Chicago on Friday however I am going to be on vacation spending time with my family until December 29th. I will be able to ship them out then.

You probably don’t need new pistons, wouldn’t hurt though I guess just as long as those are known to be high quality and the exact right size with no variations. I would (and did) replace everything else if they’re in rough shape. Cross over pipes, bleeders, and pins included.

Thank you.

The only time I recommend replacing pistons is if they have scoring longitudinally beyond the piston seal or if there are any sharp edges which would cause failure (pitting ect).

Hope that helps!

Do you ever see the piston seals fail? That's the main thing I was thinking to take care of while the calipers are detached from any fluid lines.

Any idea when the 28/30 seals kit will be back in stock?

Bringing this back up. I have a pair of rear calipers going on that I bought used in so-so shape. They definitely have miles on them due to the paint fading but the dust seals look good.

Does anyone think I should bother with a kit like this before refinishing and plugging them in?

where do they define that term; your lifetime? their lifetime? the lifetime of the program? who knows 😃

Your ownership of the car is the understanding.

"lifetime"

Yea no I don’t have insider information 🤨 I also use the FCP lifetime replacement program obviously, I just don’t bank on it being around forever. 12 years is an eternity for a program like that so I’m just being a realist. And when you say it would be messy, what do you expect will happen? There’s no language anywhere in their terms that state how long the program will exist for or that it can’t change again. One day it’s just going to be done out of nowhere and that will be that.

keep pads fat - reduces heat to boots
use ceramic pucks - reduces heat
use titatium etc shim - same

full tilt braking = rebuild brakes once a season.

I have all sorts of fancy brake systems on my different cars - this is just the answer

Silicon boots better than rubber

It's been around since 2012. I thought you might have insider information we normal folk don't have but it's just a hunch. It doesn't make any sense as a company to remove it when one of their bigger competitors now offer lifetime and with the pretense of selling all your parts since 2012 with a lifetime guarantee to all of a sudden disappear. That would be messy.

I dunno, I just don't bank on things like that lasting forever.

II'll def buy their giro disc for the fronts to try and help with the cooling of the brakes, even with ducting it was still very warm on zcpo rotors. If I had the fronts on lifetime I wouldn't care but got them used.

You can swap dust boots with the caliper still on the car. Have done it like four times now...

Good to know, I will keep the setup I have now, Spoke to Ian offline and convinced me to hold on esp with how much i track. What is the consensus for which boots held up the most?

Ill do everything I can to help with cooling, GIRO Titanium plates, GIRO Disc rotors and cooling. AP Kit is nice but out of my scope for my means

Dunno if it’s just me but I feel like that program is going to end kinda soon.

what makes you think that? Are there any signs? They have a page that pushes this and they have ECS to compete with. ECS is doing lifetime warranty now. I still think its like Costco. How many people buy a spatula, 1000? 10000? How many of that actually return it? <1%? I feel its the same with the warranty program, most parts last longer than their ownership.

I'd prefer to make this kit work, with giro discs and pads from fcpeuro. That lifetime is hard to beat.

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 😂
