ABSTRACT:
In a process for attaching a shunt wire to a carbon brush body in which a resin-containing cement is tamped into a cavity in the brush body, an improved cement is used, formed from a mixture of polyphenylene sulfide powder having a grain size of 5 to 50 μm and copper-based powder. The brush produced thereby is improved in resistance to alcohol-containing fuels.
