Test Values And Wear Limits - 20-Inch
WARNING: This page is about a different car, the 2020 Porsche Panamera, 2019 Porsche Panamera, 2018 Porsche Panamera, and 2017 Porsche Panamera. However, it is still accessible from the selected car via links, so may be relevant.
Information
The following condition criteria can make replacement necessary depending on the wear of the PCCB brake discs (new generation without indicators in the friction surface):
- Too many damaged carbon fibres in the PCCB brake disc (wear caused by the effects of temperature).
- Check PCCB brake discs while complying with the measuring prerequisites using VAS 6813 Tester for PCCB brake discs.
- It is no longer necessary to check the brake disc minimum thickness for this generation of brake discs.
| Location | Description | Type | Basic value | Tolerance |
|---|---|---|---|---|
| Pad thickness, front | Wear limit 2 mm | approx. 8.4 mm | ||
| Pad thickness, rear | Wear limit 2 mm | approx. 11.9 mm | ||
| Wear limit of front and rear brake discs | Measure using VAS 6813 test equipment. Note measuring prerequisites. New values/wear values and three measuring points are lasered onto the brake disc hub. Wear value reached: Replace PCCB brake discs on both sides of the axle. | Measured value | XX/XX Read value on brake disc hub | |
| Thickness tolerance of brake discs (max.) | Measured value | 0.02 mm | ||
| Lateral runout of brake disc (max.) | Measured value | 0.03 mm | ||
| Lateral runout of wheel hub (max.) | Measured value | 0.03 mm | ||
| Lateral runout of brake disc when installed (max.) | Measured value | 0.06 mm |
