Ceramic Brake Rotor, Determining Wear
CERAMIC BRAKE ROTOR, DETERMINING WEAR USING Carbon-Ceramic Brake Wear Tester
Checking the Connection Area on the Brake Rotor Ring and Brake Rotor Cup:
The brake rotor ring and the brake rotor cup are attached to each other and must never be separated. Never loosen the threaded connection on the brake rotor cup.
Ceramic Brake Rotor Identification on the Brake Rotor Cup
- Running Direction
- When installing, pay attention to the running direction of the brake rotor.
- Manufacturer
- Brake Rotor Serial Production Number
- Audi Part NumberNOTE:
The Audi part number on the brake rotor is an example and will be different on each vehicle model.
- Brake Rotor Production Date
- Minimum Permissible Brake Rotor ThicknessNOTE:
The minimum permissible brake rotor thickness is different for each vehicle model.
- Refer to BRAKE ROTOR THICKNESS, CHECKING
- Weight of Brake Rotor and Cup
Not Stamped-On All Brake Rotors
- The brake rotor does not have to be weighed for this model
Clean the Brake Rotor before Determining the Wear.
Never clean the brake rotor with water or any other fluid. This will falsify the measurement result.
Always wear a mouth and nose mask when using compressed air to clean the brake rotor and the brake system.
If a brake rotor is damaged or worn, check the other brake rotors for damage and wear.
