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

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)! •
