The Meritor Type 20 Air Brake Chamber is a long-stroke S-cam drum brake service chamber with a 2.25-inch stroke and 8.00-inch push rod. Its 5/8-18 UNF thread, threaded clevis, and Type 20 model identity give brake service teams clear installation details before the chamber goes on the vehicle. The assembly belongs at the actuator position, where the chamber package must match the brake layout rather than the valve or shoe set. Meritor A693276T20 gives S-cam brake service a complete chamber assembly with defined rod, stroke, and thread specs.
