999 Calliper Bolt Torque

Discussion in '749 / 999' started by TheJackal, Jan 27, 2023.

  1. Anyone know the torque spec for the bolts that hold the calliper halves together?
     
  2. Googling seems to suggest 32NM and blue loctite.

    Can anyone confirm?
     
  3. doesn't appear to be in the service manual...
     
  4. Nip it up until it goes slack then back it off half a turn, maybe put some blue Loctite on it for extra peace of mind.
     
  5. If you use the original bolts with the half height head you may struggle to get to 32Nm they are really soft and with the shallow engagement it's tricky. I put some different bolts in but I felt 25Nm was plenty, especially with the bolts going into Aluminium.
     
  6. I'll be using Ti bolts with half height heads so not sure if I should go with 32Nm or 25Nm

  7. It's not a service item. Iirc, they're M8 so 25Nm should be about right. I wouldn't go to 32Nm as you don't know the tensile grade of the Ti bolts.
