Perging noise
I own a 94.5 7.3 psd F450 and the other day when I shut the truck off I could here this perging noise,at first I thought it might be the brakes but when I pushed the clutch in the sound stopped when I released the pedal it started again.Does this mean there is air in the system,if so how do I bleed it out.
