BRAKES
• Cautiously feel each wheel hub and drum. Wheel hub or drum may be hot. Failure to follow this
warning may result in burns.
• Wipe clean excessive lubricant in area of brake shoe linings to avoid grease soaking the linings.
Replace grease soaked brake shoe linings. Failure to follow this warning may cause brakes to
malfunction, resulting in serious injury or death to personnel.
• Wear safety goggles and face shield when performing leakage tests on valves. Failure to follow this
warning may result in serious eye injury due to high pressure air.
• DO NOT use a drum that exceeds maximum wear specifications. Failure to follow this warning may
result in brake failure and serious injury or death to personnel.
• DO NOT cage brake chamber spring until chock blocks are properly positioned at wheels. Once
brake chamber springs are caged, semitrailer is without brakes and can roll. Failure to properly
chock wheels may result in serious injury or death to personnel.

provide support, as required. If air lines rub, a leak may develop resulting in brake lockup and
possible serious injury or death to personnel.
