Brake Rotor Thickness
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.
-- Clean The Brake Rotor Before Determining The Wear.
NOTE:
The Brake Rotor Vent Holes Must Be Free Of Brake Dust And Dirt. It May Be Necessary To Use A Suitable Tool To Carefully Clean The Holes. Do Not Use Any Force When Doing So.
WARNING:
Health Risk.
- Always wear a mouth and nose mask when using compressed air to clean the ceramic brake rotor.
-- Clean the brake rotors thoroughly with compressed air between the cooling channels and the vent holes.
-- To determine brake rotor wear:
- 1. Brake Rotor Thickness, Checking for Wear
- 2. Wear Indicators, Checking
- 3. Brake Rotor, Weighing
| 1. Check the brake rotor thickness. Refer to BRAKE ROTOR THICKNESS, CHECKING FOR WEAR . | |||
| If the brake rotor thickness is within the permissible range → then the brake rotor is OK | |||
| the thickness of the brake rotor is in the critical range: minimum Th. + 0.2 mm | when reaching or not reaching the threshold | ||
| ↓↓ | ↓↓ | ||
| Further brake rotor evaluation at the wear indicators | Replacing the brake rotor | ||
| ↓↓ | ---------- | ||
| 2. Use the wear indicators to check the brake rotor wear. Refer to WEAR INDICATORS, CHECKING . | |||
| If none of the six wear indicators are burned out → then the brake rotor is OK. | |||
| ---------- | One of the six wear indicators is completely burned out | ||
| --------- | ↓↓ | ||
| ---------- | Replacing the brake rotor | ||
Additional checking:
WARNING:
Risk Of Accident Due To Insufficient Braking Effect.
- Ceramic brakes should be replaced when, one of the defined wear limits is reached. The brake rotor can no longer be driven.
Risk of accident due to uneven braking.
- Always replace brake rotors on both sides of the axle.
- Brake pads likewise must be replaced on both sides of the axle.
