The Brake Spring Chamber with OEM number 1-48250842-0 (without hyphen 1482508420) is a verified direct-fit replacement for ISUZU CXZ05 series heavy trucks equipped with the 6WF1 diesel engine. This component is essential for mixer trucks, pump trucks, and other construction vehicles, serving as the core actuator of the air brake system.
The chamber combines service brake and spring energy storage functions: compressed air activates the diaphragm and push rod for braking force, while loss of air pressure triggers automatic parking/emergency brake engagement for fail-safe protection.

Important Compatibility Notes:
- Confirm left/right side installation position before ordering
- 1-48250842-0 and 1-48250841-0 are different side versions and are not interchangeable
- Different years and chassis configurations may vary; provide VIN or chassis number for final confirmation
- Continuous air leak: Hissing sound around chamber housing with pressure drop
- Weak or delayed braking: Insufficient braking force with longer stopping distance
- Park brake will not release or stays locked: Broken or corroded internal spring
- Uneven braking pull to one side: Vehicle pulls during braking due to uneven force
- Brake drag: Wheels retain partial braking after pedal release
- Failure to hold air pressure at rest: System pressure continuously drops when stationary
The spring brake chamber contains a powerful pre-loaded spring. Before disassembly, the spring MUST be caged using a caging bolt. Failure to properly cage the spring before removing the chamber can cause the spring to eject with lethal force, resulting in serious personal injury.
Professional installation with specified tools is strongly recommended.

Resists high pressure and corrosion with reliable clamp band seal
Ensures efficient air pressure transfer and responsive braking
Ensures sufficient parking brake force after long-term use
Direct bolt-on fit without modification
Every unit air-tightness and functionally tested before shipment
Reference ISUZU Workshop Manual for complete procedures:
- Lift and safely support the vehicle; remove the rear wheel
- Cage the spring brake chamber using a caging bolt
- Disconnect air line fittings from the chamber; mark line positions
- Remove chamber mounting bolts and extract the old chamber

- Connect air lines and remove the caging bolt
- Adjust push rod stroke to specified range
- Perform air-tightness check on the brake system to confirm no leaks
- Road test to confirm proper braking with no pull or drag
- Inspect chamber air tightness and push rod stroke every 10,000 km or at every brake service
- Inspect diaphragm and spring condition every 2 years or per fleet maintenance schedule
- Service immediately if continuous air leak, reduced braking force, or park brake release failure is detected
- Neutral carton packaging with individual shockproof wrapping
- Custom branded packaging available (authorization letter required)
- Suitable for: ISUZU truck repair shops, parts wholesalers, fleet maintenance departments
