Air Brake Chamber Bracket
Mack

The air brake chamber bracket provides a robust mounting point for the brake chamber, balancing strength, alignment, and vibration resistance to ensure consistent braking force. Proper bracket selection supports correct chamber orientation, which is crucial for stroke alignment, pushrod travel, and brake response time. This component must tolerate high pressures and repeated flexing without cracking or fatigue, while remaining securely attached to the vehicle structure. Installation requires accurate hole alignment, secure fasteners, and attention to corrosion protection in exposed environments. A well‑torqued bracket helps prevent misalignment that can cause uneven braking, noise, or extended stop distance. In service, inspect for deformation or corrosion, and replace if the chamber’s travel path appears restricted. Source One Parts Center.
