Slack Adjuster
Bendix

Slack adjuster assembly converts air pressure into mechanical leverage to apply brakes and maintain even shoe clearance across axles. The design features an arm length of 6 in and a spline diameter of 1.50 in, enabling precise engagement with the push rod and drum brake mechanism. Operating temperature range from -40 to 158 degrees Fahrenheit ensures reliable performance in extreme climates. The unit is rated for a torque of 23,000 in-lb and uses a straight lubrication fitting to facilitate routine maintenance and lubrication scheduling. With ten splines, it mates with standardized drive pins and lever interfaces used in heavy-duty braking systems. This component belongs to the 42848 category and aligns with Bendix specifications identified by VMRS 013-017-005. In service, technicians rely on this adjuster to maintain proper brake shoe clearance, compensate for wear, and reduce pedal travel fluctuations, contributing to predictable braking response, longer brake life, and safer performance under heavy loads or long-duty cycles.
