We are a small electric vehicle company looking to use 4 drum brake assemblies (Akebono) on our vehicle. We need the complete assembly with backing plate, with shoes and all the parts. We need the drums (5 bolt wheels). We also need the NSK rear wheel integral bearing. Potential volumes will reach 30,000 car sets (or 120,000 drums assemblies)Can you supply these parts? or do you know someone who can?
