Frequently Asked Questions

Find answers to common questions about our products and services.

What is the working principle of the Air Brake Chamber?

The air brake chamber converts compressed air pressure into mechanical force to actuate the brake shoes. When air is supplied, it pushes a diaphragm that moves the push rod, applying the brakes. A return spring retracts the mechanism when air pressure is released.

Is the clutch booster suitable for stop-and-go traffic?

Yes, our clutch boosters are specifically designed to reduce pedal effort in frequent shifting conditions, making them ideal for urban driving and stop-and-go traffic, enhancing driver comfort and reducing fatigue.

Why is the clutch pedal struggling?

Possible causes include a high-tension return spring, damaged clutch booster cylinder, low compressed air pressure, or issues with the linkage system. Our technical team can assist in diagnosing and resolving such issues.

Do you offer custom OEM manufacturing?

Yes, we are a designated OEM manufacturer and can produce parts based on customer drawings and samples. Our R&D team supports custom design and prototyping for specific vehicle applications.
