Explanation Of 2-Part Brake Disc

  1. 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-  .

  2. Only the complete brake disc is available as a spare part (disc + brake-disc chamber)!
  3. Do not separate the brake-disc chamber -2-  and brake disc -1-  . In addition, the screws -3-  must not be turned and should not need to be turned. The screws are prevented from turning by compression in the bushing.
  4. 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.
