Test Values And Wear Limits - 21 -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 |
|---|---|---|---|---|
| Front pad thickness | Wear limit 2 mm | Set value | approx. 9 mm | |
| Rear pad thickness | Wear limit 2 mm | Set value | approx. 11.3 mm | |
| Front and rear brake disc wear limit | Measure using VAS 6813 Tester. Observe 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 each axle. | Measured value | XX/XX Read off values on the brake disc pot | |
