Ah, squeaky brakes is known as the mating call of the VS800- the stock brake pads and shims are poor, so they vibrate and squeal. Cleaning will have very little, and very temporary, effect. Get some spray on brake cleaner, and spray everything down. Then take the caliper off, and put a SMALL drop of “high-temp waterproof brake grease” (available at the auto parts store for $1) on each the pins that the pads slide on. Also get a SBS Brake Pad Shim Set (part number #9500, about $6), which are composite and have an adhesive back so they will not vibrate. Peel and stick to the back of the brake pads, and between the two you will eliminate most of the brake noise. Taking a file and slightly chamfering the leading and trailing edges of the brake pads often helps also. When your brakes wear out get some better quality aftermarket pads, from EBC or SBS- even most dealers don’t put OEM pads back on.
