The PAI EM30300-001 is a brake spring with clevis assembly featuring a 1-1/2-inch stroke, 10-inch pushrod, and 30/30 type. As heavy duty diesel truck parts, spring brakes use stored spring force to apply the parking or emergency brake when air pressure is released, while the pushrod transfers movement to the foundation brake. The permanently sealed design and specified dimensions provide important identification details for matching this assembly, and MACK lists 19QE441RP1 as the OEM reference.
