- **Caution**: 

### Q: What materials are used in brake rigging for durability?
**A**: Brake rigging is typically constructed from carbon steel or alloy steel to withstand high stress and corrosion in demanding motor vehicle applications.

### Q: How does brake rigging transmit force in a bogie system?
**A**: The mechanical linkage system transfers braking force from the brake cylinder through components like brake beams, levers, and rods to activate brake shoes or pads on each bogie wheel.

### Q: What maintenance does brake rigging require?
**A**: Regular inspection of components like slack adjusters, rods, and levers for wear, proper lubrication, and adjustment ensures optimal braking performance and safety.

## 6. Manufacturing Compliance
- ISO 12100:2010 - SAFETY OF MACHINERY
