Air Brake Chambers & Diaphragms

Reliable Actuation for Heavy-Duty Safety

In an air brake system, the Brake Chamber is the actuator that converts compressed air into the mechanical force that stops the vehicle. At Victory Technology, we manufacture actuators that fleet operators trust for their stopping power and longevity. Whether you are replacing a rusted chamber on a dump truck or rebuilding units with new diaphragms, we provide OEM-level quality at factory-direct prices.

Our Product Lineup:

  • Spring Brake Chambers (Dual Chambers): Our flagship Type 30/30 and Type 24/30 assemblies combine service braking and parking/emergency braking in one unit. Featuring a fail-safe power spring and chemically treated housing, they offer superior protection against corrosion and spring fatigue.

  • Service Brake Chambers: Compact and powerful, our single-chamber actuators (Type 20, 24, 30) provide responsive service braking for steer and trailer axles.

  • Rubber Brake Diaphragms: The heart of the chamber. Our replacement diaphragms are molded from premium EPDM/NBR rubber with heavy-duty fabric reinforcement. Tested to withstand over 1 million flex cycles, they stay flexible in arctic cold (-40°C) and resist heat in demanding stop-and-go traffic.

Engineered for Performance

  • Precision Fit: Designed to match standard bolt patterns and push-rod lengths for easy installation.

  • Corrosion Resistance: Chambers feature zinc-plated or powder-coated steel housings to withstand road salt and moisture.

  • Standards: Built to meet SAE J1469 and FMVSS 121 requirements for commercial vehicle safety.
