The problem
Certain medium duty trucks equipped sr-7 bendix brake valves, the check valve inside the valve cavity May not properly set, causing internal air leakage. If the check valve does not properly seat, the resulting leakage can cause a delay in the application of the spring brakes to park the vehicle after operator pulls the dash valve button.
The risk
The delayed parking brake application can occur without warning, leading to unintended vehicle rollaway increasing the risk of a crash.
The fix
Dealers will inspect the valves and replace it free of charge. The recall began on July 31, 2006. Owners May contact Chevrolet at 1-800-630-2438, GMC at 1-866-996-9463, or Isuzu at 1-800-255-6727.
