Brake Rotor Thickness, Determining By Weighing, With Stamped Minimum Weight
Special tools and workshop equipment required
- Commercially available scale with a measuring exactness of up to ±1 gram.
- Here the minimum weight of the brake rotor is stamped "min.weight", there is no tolerance. If the stamped-on minimum weight is not reached, replace the brake rotor.
- Additional checking of the brake rotor is not necessary.
Procedure
-- Remove the brake rotor to weigh it.
- Clean and dry the brake rotor before weighing it.
CAUTION:
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.
CAUTION:
Risk of false results.
- Never clean the brake rotor with water or any other fluid.
- The brake rotor vent holes must be free of dirt. It may be necessary to use a suitable tool to carefully clean the holes.
- Clean the brake rotors thoroughly with compressed air between the cooling channels and the vent holes.
-- Carefully lay the clean brake rotor on the scale.
- Here the minimum weight of the brake rotor is stamped on the brake rotor cup, there is no tolerance. If the stamped-on minimum weight has been reached or falls short, replace the brake rotor.
- Additional checking of the brake rotor is not necessary.
If There Is Abrasion Both Brake Rotors on Both Sides of the Axle Must Always Be Replaced.
CAUTION:
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.
If there is abrasion always replace the brake rotors on both sides of the axle.
Brake pads likewise must be replaced on both sides of the axle.
