Oshkosh Corporation (Oshkosh) is recalling certain Bendix Pressure Switches, part number 4133101, sold as aftermarket parts. The plastic threads holding the two halves of the pressure switch may strip when the switch is pressurized, resulting in an air leak which, if severe enough, can cause the air system to lose pressure when the brakes are applied. Failure of the front and rear brake switches will also result in a loss of brake light functionality.
