Information

Validity (of measuring method using test equipment VAS 6813) for PCCB brake discs with new friction coating technology. Used for the first time on the 911 Turbo (991) and 911 GT3 (991). Recognizable by the three markings and values lasered at an offset of 120° (on the brake disc hub) -arrows- .

VAS 6813 is used to measure the damage to the carbon fibre-reinforced material. The lower this value, the more carbon fibres in the internal structure of the brake disc are damaged (wear caused by the effects of temperature).
The markings consist of the measuring point numbers 1 to 3 -X- (figure shows number 1), the measurement marking -1- (line), the new value -2- and the wear value -3- .
If one of the three wear values is reached or if the measured value is less than one of the three wear values, replace the brake discs on each axle.

Wear indicator plates -arrows- on the friction surfaces are no longer required with the new friction coating technology.
