Regardless of the overall state of wear, the
disc must be replaced if it shows signs of
damage around the edge.
Any unauthorised mechanical work on the
holes in the surface of the disc may
damage the brake disc itself.
If necessary, clean the holes in the disc
brake and the friction surface of the rotor
with a pressure cleaner.
Do not perform any mechanical work on the
holes in the disc.
CAUTION
When using pressure cleaners to clean discs, use
adequate face protection.
When assessing damage to the disc edges,
apply the following criteria:
maximum permissible width/depth
2 mm
;
maximum permissible length
(10 mm)
;
no more than
3
damaged areas are permissible.
Check CCM brake pad wear
After particularly intense use on the track, check the appearance of the pads as well as checking
normally for wear. If there is a distinct white discolouration on the edges of the pads, which extends
almost as far as the metal backing plate, the pads must be replaced to ensure that the brake
system continues to perform correctly.
CCM brake disc wear
As the discs wear, their mass reduces. This is due to two simultaneous effects - a thermal effect, which burns
the carbon fibres, and a mechanical abrasion effect between the disc and pad.
The instrument panel operating software uses an algorithm to calculate, in relation to effective vehicle usage
(e.g.: deceleration caused by braking), separate wear indices for the front
P(a)
and rear
P(p)
carbon brake
discs, expressed as a percentage (%) of wear.
These indices are periodically compared against a threshold value
(100%)
. Upon reaching this threshold, an
amber warning signal (possible danger of disc failure) is shown on the TFT display, warning the user that
