Test Values And Wear Limits - 20-Inch
WARNING: This page is about a different variant/trim than selected.
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 | ||
