Information On The Test Steps

WARNING: This page is about a different variant/trim than selected.

Checking involves the following tasks:

Determine current actual values (wear condition) using > VAS 6813 - tester for PCCB brake discs (at the three measurement markings).
Align/position tester VAS 6813 -1- using a laser beam -2- at the measurement marking.

Observe the required conditions! See:

> 465102 Checking front PCCB brake discs (wear assessment using tester VAS 6813) - section on "CHECKING "
Visual inspection of the brake disc friction surfaces for surface changes.
Flaking/fractures as a result of unusual usage conditions (e.g. stone chip damage).

Max. 1.0 cm² permitted!

Surface roughness (Rk) (max. 80 μm permitted) since this affects braking comfort (noises), braking behaviour/pedal pressure and brake pad service life.

Information
- Brake disc minimum thickness no longer needs to be checked (measurement no longer shown on brake disc hub).
Information
- Irrespective of wear, a brake disc may need to be changed due to edge damage on the brake disc friction surfaces.
- In this case, only one brake disc can be replaced if the measured value (determined using test equipment VAS 6813) and the friction surface of the other PCCB brake disc are still perfectly OK.
Check brake discs for edge damage > Edge damage on PCCB brake disc (damage due to improper use).
