Explanation of 2−part brake disc
• The PCCB brake discs consist of two parts on the front and rear axles. The brake disc −1− is screwed
to the brake−disc chamber −2− with 10 screws (M6) −3− .
The complete brake disc only is available as a spare part (disc + brake−disc chamber)!
•
• Do not separate the brake−disc chamber −2− and brake disc −1− from each other. It is also not
permissible and not necessary to turn the screws −3− . The screws are safeguarded against turning by
compression in the bushing.
• It is essential that the tightening torque of the 10 screws is not changed (do not turn the screws) as this
will have a negative effect on the sound behaviour.

Note
• Do not confuse right and left brake discs during assembly! Distinguishing characteristic: Involute
shape, identification and spare part number (SP No.)!
• The front PCCB brake discs of the Turbo and GT2 are different. Use the correct brake disc when
replacing!
• The front PCCB brake discs are marked with GT or Turbo, R = right or L = left and with an arrow for
the direction of rotation (additional diffence to right or left)!
• Spare part on left−hand side − third group number is odd. Example: SP No. Left brake disc =
996.351.031.92.
• Spare part on right−hand side − third group number is even. Example: SP No. Right brake disc=
996.351.032.92.
