WRECKER TOWING
WARNING:To reduce the risk of personal injury or property
damage when manually releasing the spring brakes, be sure to
block the wheels so the vehicle cannot move once the brakes are
released.
Note:Make sure to connect your vehicle securely to the tow vehicle and
that the tow vehicle’s parking brakes are set before releasing the disabled
vehicle’s spring brakes.
Before moving the disabled vehicle, check for adequate road clearance of
vehicle components. If possible, unload the disabled vehicle before
towing. This reduces any abnormal load to the vehicle components
resulting from the towing procedures. Before towing, make sure to
release the parking brake fully. You can reset the spring-actuated type
parking brake by recharging the air system with at least 64 psi (441 kPa)
of air. If the brake system does not retain air pressure, then you must
release the spring brakes manually. SeeParking brakein theBrakes
chapter.
