Inspections And Lubrication
Figure 8-3 Drain Trailer Air Tanks
8.2.4 INSPECT, MEASURE AND ADJUST BRAKES Inspect and measure the brake linings. Replace with a quality shoe and lining if contaminated, cracked or if the lining is worn to less than ¼ inch thickness at any point. See figure 8-4.
Figure 8-4 Measure Brake Lining Chock tires and release brakes. Measure the distance (A) with brakes released. See figure 8-5. Use a lever to move slack adjuster until brakes contact the drum and measure the distance (B). Subtract distance A from distance B. The result is the free stroke. Adjust slack adjuster so the free stroke is 3/8 – 5/8 inch on each slack adjuster.
