disc replacement is necessary.
The user is warned of this condition by the appearance of the message: "CCM brake discs worn" on the
display, together with the specific amber symbol. At the end of the display cycle, or when the MODE
button is pressed (with "Escape" function), the symbol is reduced to icon form.
An RLI for "Number of brake disc replacements" is also generated, identifying the number of times that the
discs have been replaced.
Once the brake discs have been replaced, the wear index may be reset on the instrument panel.
The wear index indicated on the instrument panel may only be reset when the discs are replaced,
once the wear index exceeds 100%.
To maintain a record of the latest brake wear index reset, three values are stored in the statistics memory for
the front and rear brakes, which are updated upon reset (with the possibility of storing the last seven
resets):
Number of brake disc changes counter: --------- (dimensionless number)
Kilometres at first disc brake change: --------- Km
Wear percentage at first disc brake change: --------- %
At each service, submit the following data (printing out the parameters from the instrument panel):
vehicle serial number;
vehicle mileage ("Odometer" parameter);
"Disc Wear Index" value.
There are essentially 5 different scenarios possible:
1 - Replacing all carbon discs due to vehicle usage;
2 - Replacing one carbon disc (or two discs on same axle) due to failure;
3 - Replacing a working instrument panel (dialogue with diagnostic instrument possible);
4 - Replacing of a malfunctioning instrument panel (dialogue with diagnostic instrument not possible);
5 - Replacing the carbon discs before reaching wear threshold ("Disc Wear Index" parameter < 100%).
1 - Replacing the carbon discs due to vehicle usage
In this situation, the amber warning signal on the TFT display is lit.
Use the diagnostic instrument to verify from the instrument panel that the disc wear index has exceeded
100%.
Replace the carbon discs.
Reset the carbon disc wear index on the instrument panel with the diagnostic instrument.
2 - Replacing one carbon disc (or two discs on same axle) due to failure
In this situation, only one disc (or two discs on the same axle) are replaced, without modifying the
parameters on the instrument panel.
In other terms, the "Disc Wear Index" parameter is left at the value for the discs not being replaced
(partially worn).
3 - Replacing a working instrument panel (dialogue with diagnostic instrument possible)
