1
00:00:00,000 --> 00:00:05,125
Inspect brake linkage for missing, broken, or loose parts.

2
00:00:05,125 --> 00:00:10,917
Also, inspect for badly worn pins, bushings, or wear plates.

3
00:00:10,917 --> 00:00:14,125
Repair or replace parts, as necessary.

4
00:00:14,125 --> 00:00:19,375
Check the brake rigging wear plates on the hangers and the truck frame pads.

5
00:00:19,375 --> 00:00:29,125
Replace wear plates when the working clearance between the wear plate and the mating wear surface exceeds 0.19 inches (4.8 mm).

6
00:00:29,125 --> 00:00:32,708
Check the clearance between brake shoes and wheels.

7
00:00:32,708 --> 00:00:44,333
If clearance is more than 0.75 inches (19 mm), readjust the brake system as discussed in the Brake System Adjustment section of this module.

8
00:00:44,333 --> 00:00:56,000
<b>Note: </b>The 0.75 inch (19 mm) clearance is needed to ensure that the brake shoes do not ride on the wheels while the truck is steering through curves.

9
00:00:56,000 --> 00:01:05,833
<b>Note: </b>The maximum allowable brake-cylinder piston-rod travel is 6.5 inches (165 mm).

10
00:01:05,833 --> 00:01:10,750
Check the brake cylinder piston-rod travel that is required to engage the brake.

11
00:01:10,750 --> 00:01:24,458
If the piston-rod travel is 6.5 inches (165 mm) or more, readjust the brake system as discussed in the Brake System Adjustment section of this module.
