- Cost: Diaphragm clutches are more expensive to manufacture than other types of clutches, such as coil spring clutches.
- Durability: Diaphragm clutches are not as durable as other types of clutches, and they can wear out more quickly, especially in high-performance applications.
- Noise: Diaphragm clutches can be noisy, especially when they are worn out.
- Complexity: Diaphragm clutches are more complex to design and manufacture than other types of clutches.
For these reasons, diaphragm clutches are not as popular as they once were, and they are rarely used in modern vehicles.
