I wouldn't go to the expense of replacing the calipers.

If they are leaking, replacing the inner seals isn't that difficult.

Does anyone have experience replacing stock 996 calipers with cayman S calipers?

Thanks guys, the lines and brake master cylinder are new, the car is tracked and the pedal is still mushy, I hope to replace the tired calipers with the cayman s ones if they fit and use my current rotors and mounts....

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Does anyone have experience replacing stock 996 calipers with cayman S calipers? If so will the stock 996 rotors still be usable ? I'm trying to fix a soft brake pedal without buying a new full brake kit. The car is 2002 C2, thanks Ken
SS lines are fine, but there is no reason stock lines in good shape would give anything other than a solid feel
dont go crazy - find the problem and fix THAT with good stock parts (unless you are tracking the hell out of it. in which case you would already have done most of these things - which is why I for one would prefer to buy a car that has been tracked over some street roller)
Due to the low post number, my guess is this maybe a case of not being used to the linear feel (v. overboosted) of Porsche brakes. However a join date of Mar 2005, makes me think maybe there is something amiss.
Flush would be the "cheapest fix" and would be part of any of the solutions as a whole.

this whole thing is a train wreck
caliper flex?
WTH - am running 25 year old calipers and they are fine
when ar ethe soft? (at track - street)
what pads
what fluid
how often do you bleed
how do you brake (freeway sissy style or with purpose)
I would stop messing around with thoughts of caliper and or rotor swapping for boxster or cayman or hypothalamus parts and fix what is wrong with your set up
I agree Steve - caliper rebuild or maybe the new MC was installed without a proper beeding of the whole system...ABS and clutch slave
but tossing used Cayman parts at the problem is not a good approach IMO
Not much can go wrong with a caliper that wouldn't be readily apparent. At the end of the day they are just plumbing. If they aren't leaking and you don't have a stuck piston, not much to go wrong. If they are leaking, replacing the inner seals isn't that difficult. I wouldn't go to the expense of replacing the calipers.
Stay AWAY from as brake lines for street use. They are not made for everyday use. Things made for the race track and made for the race track, light and made to last a race. If you rub thru the SS there is nothing holding the pressure in the line and it will pop. One of our 928 guys was killed do to this exact issue. Yes they look cool and high tech. But are not made for everyday street use.
