MACK 21090156 Part Description
Manufacturer
Features & Benefits
- Clamp band secures the chamber halves against air pressure
- Delivers consistent push-rod travel across repeated brake applications
- Matched stroke length preserves designed brake leverage at the axle
- Sealed housing keeps moisture from reaching the internal diaphragm
Mack Air Brake Chamber
Convert brake-system air pressure into mechanical push-rod force with the Mack Air Brake Chamber. A diaphragm inside the housing flexes as pressure builds, driving the push rod outward to apply the brake through the slack adjuster. The chamber mounts to the axle's factory bracket using the same bolt pattern and stroke length as the original unit. Matching that stroke length with the Mack 21090156 keeps the brake's mechanical advantage within its designed range after installation.
