After driving about 10 miles a moaning sound starts when slowing down but stops when brakes are applied starts again when begin to go again (forward only ,not in reverse) if engine is shut off process starts over no codes any help would be appreciated

 

Sounds like a Brake Caliper problem -- may need lubrication of the Caliper Bolts. MUST use High-Temperature grease !!
Wheel Bearing failure is VERY RARE, but possible.

Right Front Brakes - ACDelco Drilled & Slotted Rotors; Eclipse Calipers; Police Pads; ESI-6 Brake Fluid; Raybestos Hoses.
