📌 Product Overview
The Heart of Air Brake Safety.
Reliable braking isn’t optional—it’s essential. Victory Technology’s Spring Brake Chamber is a heavy-duty dual-chamber actuator designed to provide both Service Braking (for normal stopping) and Parking/Emergency Braking (fail-safe holding) in one robust unit.
Engineered in our Zhuji Aoke facility, these chambers are built to withstand the harshest road conditions. Featuring a Zinc-Plated or Powder-Coated Steel Housing, they offer superior resistance to road salt and corrosion. Inside, a high-cycle Power Spring ensures that if air pressure is lost, the mechanical spring automatically engages the brakes, providing fail-safe security for trucks, trailers, and buses.1
🔹 Why Choose Victory Spring Brake Chambers?
- ✅ Dual-Chamber Reliability:Combines the Service Brake chamber and the Spring Brake (Parking) chamber into a single, integrated unit.2 It delivers instant response for highway braking and powerful holding force for parking.
- ✅ Industry Standard Compatibility:Available in the most common configurations, including Type 30/30 (Standard & Long Stroke), Type 24/30, and Type 24/24. Designed to fit standard heavy-duty axles on North American and European rigs.
- ✅ Fail-Safe Power Spring:Safety is built-in. The high-tension internal spring is chemically treated for fatigue resistance, ensuring it won’t lose tension over time. It provides immediate mechanical braking power if the air system fails.
- ✅ Weather-Sealed Durability:The housing is crimped and sealed to prevent dirt, moisture, and salt from entering the chamber, protecting the internal diaphragm and push rod from premature wear.

❓ Frequently Asked Questions (FAQ)
Q: What is a Type 30/30 chamber?
A: It refers to the size of the effective area of the diaphragms. A “30/30” has a 30 sq. in. service chamber and a 30 sq. in. parking chamber. It is the most common size for modern trailers.
Q: Does it come “Caged”?
A: Yes. For safety during shipping and installation, the power spring is mechanically compressed (caged) with a caging bolt. Warning: Always read safety instructions before removing the caging bolt.
Q: Is the push rod adjustable?
A: The push rod typically comes in a standard long length (e.g., 8-12 inches) and is designed to be cut to size by the installer to fit the specific slack adjuster setup.
