    What is going on in the video, is they are placing moped or motor scooter brake shoe castings into the mold then filling it with the powdered friction material the piece of white material is there to keep the friction material from bonding to the press die. Under high enough pressure the powder becomes solid forming the friction part of the brake shoes. This process is much the same as cutting inserts and pressed metal parts such as gears and couplers are made.
    Never try to tell me it can't be done
    When I have to paint I use KBS products

    Thanks Frank,

    I suspected that was the case, but I had it in my head that the friction media was thermoset resin based, not pressure consolidated material. I guess the same pressure consolidation which makes the friction material stick to itself, also makes it stick to the castings.
