The issue
On certain B700, C600, CL9000, F700, LN600 and W9000 vehicles equipped with eaton anti-lock air brake controllers and produced at the kentucky turck plant. A nylon piston within the pneumatic valve system can increase in size when exposed to certain quantities of typical air brake contaminants that may accumulate due to lack of air brake maintenance. The piston could momentarily stick and/or jam in the valve housing causing a temporary or permanent loss of braking to the affected axle. v79144
