PCCB Brake Discs With New Friction Coating Technology
WARNING: This page is about a different car, the 2018 Porsche Macan and 2017 Porsche Macan. However, it is still accessible from the selected car via links, so may be relevant.

New measuring method for wear assessment. Wear assessment is performed using test equipment for PCCB brake discs WE 1578.
- Test equipment VAS 6813
- Laser beam for positioning
- Measured value display
Test equipment VAS 6813
NOTE:
- Validity (of measuring method using test equipment VAS 6813) for PCCB brake discs with new friction coating technology
. Recognisable by the three markings and values lasered at an offset of 120° (on the brake disc hub) -arrows
-.
Measurement markings with new friction coating technology
- 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 both sides of the axle
.
Markings and values (new value/wear value)
Wear indicator plates -arrows - on the friction surfaces are no longer required with the new friction coating technology.
Wear indicators no longer used
