I'm in the process of swapping
Cayman S
(
987.2
) brakes over to my base
987.2 Cayman
(partially for looks partially for better brakes) and wanted some input on the condition of the seals and pistons on the calipers I'm using. Here are my questions:
There is some minor corrosion on just one or two of the inner part of the pistons due to where the brake pad dampers were sitting, pictures below. Should I be concerned about this? I'm thinking no since this is on the outer part of the piston, but would like some reassurance as this is my first go around on a project like this.
I noticed on the front calipers the outer piston seal doesn't sit perfectly flush with the caliper. Am I correct in assuming this is normal? Both front calipers were like this and I don't see any damage to any of the outer seals. I'll also be able to get a better idea when I take my current calipers off, but until then...Pics are below.
The hard brake lines coming out of the calipers seem to have been bent a bit. Anything I should know if I'm replacing these? Threadlocker requirements, torque spec, etc.
Piston corrosion:
Outer seals, are these normal? Not perfectly flush....
That little bit of corrosion and where it is? If it helps you sleep at night hit it with some mother's mag and aluminum polish on a rag tip. As for the pistons, the seals don't appear to be leaking and they look OK in the photos. Clean, lubricate, assemble and test.
Awesome, I figured I was overthinking it, gonna clean these guys up and should be good to go. I do think I'll replace the hard brake lines coming out of the caliper as it looks like they've been bent around quite a bit. Anything I should be aware of with these? Not sure if thread locker is required or if I just tighten them down until they're snug...

You'll have to bleed the brake system, if you're going to do that you might as well replace the brake fluid in it's entirety as that is a two year interval recommendation anyway. I've never used thread lock on brake lines, other members may say differently I don't know.
Haha yeah I do know that much. No problem bleeding the brakes and cleaning up a bit of a mess from dripping fluid. Gonna go ahead and throw on new lines as well since the car is 10 years old.
No need for a mess, I have a catch, caliper nipple tubing, recycling container and a motive power bleeder, Easy peasy. In case you are unaware, those calipers have two bleeders, bleed both or you'll have residual air in the system.
Yeah I know how to bleed the brakes that's pretty straight forward. I was referring to leaking fluid from swapping out the brake lines when I swap all that out.
You should not need thread locker on the brake line fittings. And I agree, if the hard lines have been bent, best to replace them.
Quite a PITA trying to find these online. Had to call up my local dealer, quoted $170ish for a full set. The rears are only in Germany as of right now. Half tempted to use the old ones from my current calipers, but probably a good idea to just buy completely new ones for peace of mind.
Do not use thread locker on brake line fittings...
FCP Euro
may have the brake lines you need as well, they stock OEM parts
Thanks. I ended up buying a shop manual pdf online so that’ll help as a reference for some of the toque specs. It’s not much for the brake lines obviously but the caliper bolts are important.
Re: caliper bolts, if I recall correctly they are to be discarded and replaced, not reused.
