The MGM Brakes LTR-L3 3" Long Stroke series spring brake actuators have a double-diaphragm design for an increased reserve stroke, helping to reduce out-of-adjustment citations and improve braking efficiency.
A new non-coil clashing power spring provides 100 lb/445N of additional parking force (at 1.25"/32 mm of stroke) over standard 30/30 brakes. The newly engineered “weatherseal” diaphragm is designed to cover breather holes during operation, effectively sealing out contaminants.
The integral release bolt is permanently installed and cannot get lost. Made entirely of aluminum, the brake's head is lightweight and corrosion-resistant. The spring brake side of the LTR-L3 is backed by a full six-year warranty.
