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.
