Test Values And Wear Limits 20"
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 with > VAS 6813 - PCCB Brake Disc Tester while adhering to measuring requirements .
- With this generation of brake discs, there is no longer any need to check the minimum brake disc thickness .
| Use | Explanation | Type | Basic value | Tolerance 1 | Tolerance 2 |
|---|---|---|---|---|---|
| Pad thickness, front | Wear limit: 3 mm | 8 mm | |||
| Pad thickness, rear | Wear limit: 2 mm | 9 mm | |||
| Brake disc wear limit, front and rear | Measure using Tester VAS 6813. 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. | Read off values on the brake disc hub | |||
