Slack Adjuster (R806024)
Mack

The slack adjuster is a braking system component that automatically maintains the correct clearance between the brake shoes and drums as the linings wear. This unit, identified by code R806024, is designed for heavy‑duty Mack braking systems and features a rugged housing, sealed lubrication path, and an auto‑adjust mechanism that compensates for lining wear during service. As the brakes self‑adjust, pedal travel remains consistent, braking response stays predictable, and daily maintenance time is reduced. The assembly resists moisture infiltration and road debris thanks to seals and a corrosion‑resistant finish, which is critical in harsh winter and off‑road conditions. During operation, if the adjuster becomes stuck or leaks, drum wear becomes uneven and stopping power is compromised, potentially increasing stopping distance. Routine inspection should verify the push rod alignment, ensure the auto‑adjustment is functioning after servicing, and replace if the unit shows signs of wear, corrosion, or mechanical binding. When installed correctly, this component contributes to smoother braking, improved tire life, and safer highway performance. Source One Parts Center, trusted supply partner.
