Although both the Brake Friction Linings (21091) and Brake Clips (21090) are components of the YIKONG YK4107 RC Car braking system, they serve completely different purposes. The Brake Friction Linings generate the braking force, while the Brake Clips secure the brake assembly. Both components are essential for proper brake operation.
The key differences are shown below:
| Component | Brake Friction Linings (21091) | Brake Clips (21090) |
|---|---|---|
| Primary Function | Generate friction to slow and stop the vehicle | Secure the brake assembly and prevent component movement |
| How It Works | Contacts the brake mechanism to create friction | Holds and positions the brake components securely |
| Wear Item | Yes, a normal consumable part | Generally no; replace only if bent or damaged |
| Effect on Braking | Directly affects braking force and stopping distance | Affects the stability and reliability of the brake assembly |
| When to Replace | When the friction material becomes worn or braking performance decreases | When the clips become bent, loose, or damaged |
Simply put, the Brake Friction Linings (21091) are responsible for creating the stopping force, while the Brake Clips (21090) keep the braking system securely assembled. They work together to ensure the YIKONG YK4107 RC Car delivers safe, stable, and reliable braking performance.
