Corrosion of Brake Components











Corrosion protection coatings for brake components and hardware may be damaged and or stripped away (Figures 1 and 2) if highly concentrated acid-based cleaners are used. Once the corrosion protection is damaged or removed the brake components and or hardware can begin to corrode. These acid-based chemicals (Figure 3) are typically found in wheel cleaners, but may also be found in other general high strength cleaning solutions. It is imperative that only approved Mercedes-Benz paint care products and cleaners be used. Reference WIS document AP98.30-P-8070-06Y for approved paint care products and Mercedes-Benz Service Bulletin S-B-40.10/66 for an approved alkaline wheel cleaner for light alloy wheels.

Note:
Components damaged by cleaning solutions are not covered under warranty.
