Application Guide

For Lining Mix To determine the A/L factor, you need the following: Size of the brake chamber (Type 30 or Type 24) Length of slack adjuster (Measure from center of S-cam to center of clevis pin of chamber)  Size of chamber x length of slack adjuster = A/L factor   Example: Type 30 chamber x 6½ slack adjuster = 180 A/L

For Heavy Duty “S” Cam Air Brakes • Recommendations based on a 16-1/2½ x 7½ brake

Axle Load (lbs.)	195 A/L Type 30 Chamber x 6.5" Slack	180 A/L Type 30 Chamber x 6.0" Slack	165 A/L Type 30 Chamber x 5.5" Slack	144 A/L Type 24 Chamber x 6.0" Slack
