Checking With Carbon-Ceramic Brake Wear Tester: Vas6813

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2018 Audi S6, 2018 Audi A6 Quattro, 2018 Audi A6, 2017 Audi S6, and 2017 Audi A6 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

Special Tools And Workshop Equipment Required

Carbon-Ceramic Brake Wear Tester:VAS6813

NOTE:

The Check Occurs By Determining The Brake Rotor Thickness "and" The Wear Value With The :VAS6813 , Both Must Be Measured Three Times Respectively Around The Circumference.

The wear value -C- for the :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 .

NOTE:

For additional information on the :VAS6813 refer to the supplied Owner's Manual.

Measurement:

The brake rotor must be clean.
The brake rotor must be dry.

WARNING:

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.

NOTE:

The Values -A And C- Are Different Depending On The Location.

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

-- Place the :VAS6813 flush on the outer edge of the brake rotor.

-- Switch on the :VAS6813 .

-- Move the :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 :VAS6813

If one of the three wear values -C- is reached or falls short, the brake rotor must be removed for further checking.

NOTE:

The wear value -C- is different depending on the measurement location.

-- Remove the brake rotor.

-- Refer to Carbon-Ceramic Brake Wear Tester

NOTE:

To Avoid False Measurement, Place The Brake Rotor On A Non-Electrically Conductive Surface (For Example A Wooden Table).

The surface must be clean and dry

The brake rotor must be clean and dry

-- Place the :VAS6813 again flush on the outer edge of the brake rotor.

The Measurement Must Take Place Again On All Three Measurement Locations To Guarantee A Correct Check.

-- Move the :VAS6813 -1- back 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 :VAS6813

If One Of The Three Wear Values -C- Is Reached Or Falls Short The Brake Rotor Must Be Replaced.

If There Is Abrasion Both Brake Rotors On Both Sides Of The Axle Must Always Be Replaced.
