Torque values are for dry threads. Teflon tape is not considered dry for that purpose.

^ i think he meant to give the screw a better seal since theyre stripped. nor do i recommend depending on torque specs so much for every little screw

If OP messes with the three "good" calipers, he's gonna destroy what threads remain and will be forced to buy new calipers. I get the impression he is trying to delay that inevitibilty. Teflon is a lubricant, not a sealing material.

Yes, we are. It will provide some sealing but that's not its purpose.

I still question how good the supposed good calipers are.

For a brake caliper, the main sealing is at the seat where the V part of the bleeder seats against, not the threads. I imagine the bleeder screw itself is quite deformed after being squashed against it.

Thus my admonishment to watch for leaks. It would be very much better to bite the bullet and replace all four now, but...

I got the new caliper in and no leaks on any. I bled just the new caliper line and the pedal feels good. I took it out and did a bunch of hard stops and there are no leaks from any of the bleeders. I think I’m good.

Wow..... Just did this exact same thing on my set from Z1, thought it was 70ft lbs and ended up stripping most of the bolts and having leaks from the bleeder screws. Got 8 new bleeder screws on the way and just hoping I didn't strip the threads on the calipers or this would be one costly mistake.. @All G'd Up How has everything held up so far? How many new calipers were needed as well?

Oh boy. Not good. You need to remove all bleeder screws and inspect the threads

Aw man I’m sorry but glad I’m not the only one who made this mistake. It’s been over a year and about 12k miles and I have no leaks from any of my calipers, I only replaced the one that was leaking. I hope you don’t have to replace all your calipers or you’re looking at close to $1k, maybe try to find someone selling a used set or you could rethread the calipers for bigger bleeder screws. Lmk how you make out.

Once the new ones are in tomorrow gonna give them a good look and a very thorough test with the new bleeders to check for leaks. If so then 4 new red calibers will have to be ordered once again, does anyone know where to get them besides Z1? I recently just purchased the whole kit from them for about $1800 so if i need 4 new calibers thats another $1200 shoulda just went with some real bbk's at this point lol
