Explanation of 2−part brake disc
• The PCCB brake discs consist of two parts on the front and rear axles (illustration shows front brake
disc). 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
the 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.

(additional difference of right or left)!
• Spare part on left−hand side − third group number is odd. Example: SP No. Left brake disc =
