Product Description
Brake Spring Chamber 1-48250842-0 1482508420 for ISUZU CXZ05 6WF1 6WG1 Truck
Verified OEM Fit for Diesel Air Brake System
Product Overview
The Brake Spring Chamber with OEM numbers 1-48250842-0 / 1482508420 is a verified direct-fit replacement for ISUZU CXZ05 and CYZ series trucks equipped with the 6WF1 diesel engine. This component is the critical actuator in the pneumatic brake system, converting compressed air pressure into mechanical thrust to actuate the brake slack adjuster for both service braking and parking/emergency brake functions.

Installation & Maintenance
⚠️ IMPORTANT: Always cage the spring brake chamber using the caging bolt before removal. Failure to cage the power spring can cause serious injury.
Installation Steps (Reference workshop manual):
- Park vehicle on level ground, apply parking brake, chock wheels
- Release system air pressure to 0
- Fully cage the spring chamber using caging bolt (do not exceed 100 Nm / 74 ft-lbs)
- Disconnect air lines and remove mounting bolts
- Install new chamber, reconnect air lines, torque mounting bolts to specification
- Remove caging bolt, restore air pressure, test brake stroke and seal integrity
Maintenance Schedule
Inspect push rod stroke and air tightness every 50,000 km or 6 months; perform full diaphragm and clamp band inspection every 12 months.
