Brake Chamber WG4005362000 SINOTRUK HOWO
The WG4005362000 Brake Chamber is a pneumatic actuator that converts air pressure from the brake circuit into mechanical force to expand the brake shoes. As a critical component in the SINOTRUK HOWO air brake system, it ensures rapid response, consistent push force, and exceptional durability for safe and efficient braking of heavy-duty axles.
- Optimal Pneumatic Performance: The 20'/24' diaphragm type provides excellent force-to-stroke ratio, generating strong push force to overcome brake shoe return spring resistance and apply firm pressure against the drum
- Robust and Leak-Proof Construction: Stamped steel or alloy body resists corrosion and impact. Reinforced synthetic rubber diaphragm ensures perfect sealing, resisting fatigue and extreme temperature variations
- Precision Push Rod and Guiding: Threaded rod is heat-treated for high hardness and wear resistance. Precise guiding within the chamber body prevents jamming or lateral movement
Compatibility: Direct replacement for original factory part, ensuring perfect fit with the HOWO air brake system
- Safety Compliant: Meets safety standards for heavy vehicles, ensuring correct stroke essential for proper brake adjustment

Compatibility
This brake chamber is designed for:
- SINOTRUK HOWO series trucks
- HOWO T5G with VGD71S front axle
- HOWO A7 series
- Applicable for front or rear axle brake systems
Function Description
When the driver presses the brake pedal, compressed air is sent to the WG4005362000 brake chamber. The pressure pushes the diaphragm, which moves the push rod. This rod then actuates the slack adjuster lever, rotating the S-cam. The rotation of the cam expands the two brake shoes against the inner surface of the brake drum, creating the friction force that slows the vehicle.
Common Failure Symptoms
Replace this brake chamber when experiencing:
- Air leak noise from the brake chamber
- Weak or delayed braking response
- Uneven braking between wheels
- Visible diaphragm damage or cracks
- Push rod not returning to rest position
- Corrosion on the chamber body
