Fitment checklist
- Read the complete part number and stroke identification on the existing chamber.
- Compare mounting-stud spacing, pushrod/clevis dimensions and clevis-pin arrangement.
- Check air-port size, orientation and clearance against the installation.
- Confirm compatibility with the brake, slack adjuster and vehicle specifications; a Type 30/30 designation alone does not establish interchange.
World American is the supplied aftermarket brand. The Bendix reference identifies the catalog application; this is not a Bendix-branded chamber. Long stroke identifies the actuator configuration and is not a claim of increased braking force.
Installation
Use a qualified brake technician and follow the chamber and vehicle manufacturer’s procedures. Spring brake assemblies contain stored spring energy. Do not disassemble the sealed spring section.
