Abstract
To provide a method of manufacturing a friction member with high painting performance in which undesirable matters, which stick to the friction member before painting, are removed, and degreasing and recovery of damaged portions are carried out. In the method of manufacturing a friction member in which a friction material is attached to a metal back plate and they are painted, after the friction material is attached to the back plate, the back plate is treated before painting. The treating prior to painting process may be shot-blasting or coating with phosphate. With this treatment before painting, parting compounds that are adhered when the friction material is attached to the back plate is to be removed; dirty things and attached matters are removed; and flaws due to blasting are recovered, resulting in improved painting performance in adhesiveness.
