CERAMIC BRAKE ROTOR, DETERMINING WEAR USING Carbon-Ceramic Brake Wear Tester:VAS6813: Notes

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

NOTE:

This is a new test procedure to determine the wear limit of the ceramic brake rotors

The brake rotor can be identified by the following points:

The wear indicators -arrow- on the friction surface of the brake rotor are no longer present

NOTE:

The wear is determined by determining the brake rotor thickness "and" the wear value with the Carbon-Ceramic Brake Wear Tester:VAS6813 ; both must be measured three times respectively around the circumference.

On the brake rotor cup the permitted minimum thickness "min.th" of the brake rotor is engraved.

The brake rotor wear value -C- is engraved on the brake rotor cup for the Carbon-Ceramic Brake Wear Tester:VAS6813 .

Value -A- is a value from the production of the new brake rotor

The values -A and C- can be different depending on the location.

The values -A and C- can be different depending on the brake rotor.

Example of minimum thickness: -3-, brake rotor thickness. It must not fall short of this value.

NOTE:

The value -3- can be different depending on the brake rotor.
