DETERMINING WEAR USING Carbon-Ceramic Brake Wear Tester:VAS6813
Special tools and workshop equipment required
- Carbon-Ceramic Brake Wear Tester:VAS6813
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.
The wear value -C- for the Carbon-Ceramic Brake Wear Tester:VAS6813 is engraved on the brake rotor cup.
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.
Value -A- is a value from the production of the new brake rotor
- The wheel is installed.
- The brake rotor thickness is checked.
- The measuring device is checked. Refer to Carbon-Ceramic Brake Wear Tester .

- 1 On/Off button
- 2 Measured value hold button
- 3 Measured value display
- 4 Laser beam positioning tab
- 5 Interface
Additional information on the Carbon-Ceramic Brake Wear Tester:VAS6813 can be found in the supplied instructions.
Measurement:
- The brake rotor must be clean.
- The brake rotor must be dry.
There is a health risk.
- Always wear a mouth and nose mask when using compressed air to clean the ceramic brake rotor.
- Never clean the brake rotor with water or any other fluid.
At a distance of 120° the marks for the measurement for deterring the wear can be found
The following described measurement must take place on all three measurement locations to guarantee a correct check.
-A- new value, -C- wear value, -B- number of the measurement location, -D- mark for the laser beam for the measurement of the wear value.
For example the third measurement location -B- from "1 to 3" can be seen.
The values -A and C- are different depending on the location.
The values -A and C- are different depending on the brake rotor.
-- Position the carbon-ceramic brake wear tester:VAS6813 flush with the outer edge of the brake rotor.
-- Switch on the carbon-ceramic brake wear tester:VAS6813 .
-- Move the carbon-ceramic brake wear tester:VAS6813 -1- along the outer edge -2- until the laser beam points exactly on the mark -D- on the brake rotor.
-- Determine the wear on all three measurement locations of the brake rotor from "1 to 3".
-- Read the displayed value on the carbon-ceramic brake wear tester:VAS6813 .
If one of the three wear values -C- is reached or falls short, the brake rotor must be removed for further checking.
The wear value -C- is different depending on the measurement location.
-- Brake Rotor, Removing
-- Refer to Carbon-Ceramic Brake Wear Tester
To avoid a false measurement, place the brake rotor on a surface that will not conduct electricity (for example, a wooden table).
The surface must be clean and dry
The brake rotor must be clean and dry
-- Position the carbon-ceramic brake wear tester:VAS6813 flush with the outer edge of the brake rotor again.
The measurement must take place again on all three measurement locations to guarantee a correct check.
-- Move the carbon-ceramic brake wear tester:VAS6813 -1- along the outer edge -2- again until the laser beam points exactly on the mark -D- on the brake rotor.
-- Determine the wear on all three measurement locations of the brake rotor from "1 to 3".
-- Read the displayed value on the carbon-ceramic brake wear tester:VAS6813 .
If one of the three wear values -C- is reached or falls below, the brake rotor must be replaced.
If a brake rotor is damaged or worn, check the other brake rotors for damage and wear.
