inspect the braking system for warped or uneven rotor surface, as this may cause this noise and uneven pad wear. CV joints also could cause this if the boots are torn, have insufficient grease, are damaged,or have worn bearings. Hopefully this helps

sound like an internal engine problem. either one or more of the pistons has "piston slap" and that knocking will diminish as the engine warms up or possibly a rod bearing is worn out. have a tech do a manual oil pressure test to make sure the oil pump and main bearings are ok. piston slap or knock that decreases when the engine warms up is not that serious, but a rod bearing knock or possible oil pump failure should be taken care of asap.

CHECK ALL DRIVE BELT ACCESSORIES LIKE ALTERNATOR - AIR CONDITIONER COMPRESSOR AND CRANKSHAFT PULLEY.I HAVE SEEN A LOOSE OR BAD TRANSMISSION MOUNT CAUSE KNOCKING NOISE IF ENGINE ACCELERATED.
