Brake shoe for Yamaha dies are typically made using materials such as high-speed steel, carbide, or tool steel. The manufacturing process involves several steps:

1. Designing the die: The design of the die is created using computer-aided design (CAD) software.
2. Material selection: The appropriate material is selected based on the requirements of the brake shoe die.
3. Machining: The die is machined using computer numerical control (CNC) machines or other machining tools.
4. Heat treatment: The die is heat-treated to improve its hardness and durability.
5. Finishing: The die is finished using techniques such as grinding, polishing, or coating to achieve the desired surface finish.

Once the brake shoe die is manufactured, it can be used to create the actual brake shoe using a press or other manufacturing equipment.
