OK GUYS,
Made sure the vent hole was open in the MC cap. bled all 4 lines. Pedal goes down just fine when bleeding, refilled MC to top with fluid, replaced cap. Pedal is rock hard and no brakes. If I leave cap off and push on pedal, I see the silver piston move and fluid squirts up from the rear hole. Could it be that the wheel cylinders are locked up? This truck has been in the garage for about 4 years without moving or starting. How is the best/easy way to check wheel cylinders?
