## NHTSA's summary

Customer may complain of a loss of air pressure after the vehicle has been sitting parked. Some amount of pressure loss is expected and should be considered normal. Roughly 50% of parking brake valves refturned through warranty do not exhibit any faults when tested. When testing the valves for leaks, a small \(non\-audible\) amount of air leakage can be expected through the fexhaust port of the valve. Please be sure to follow the testing procedure as outlined by section BR02\-39 of the Chassis Workshop Manual under Inspection and Repair. If the amount jof air leakage is less than the test specification, do not repair or replace the parking brake valve. If the vehicle exhibits a significant loss of air pressure, inspect the rest of the air system for leaks before condemning the parking brake valve.
