ABSTRACT:
The brake drum cleaner assembly includes a water hose, and a unitary spray adapter of plastic or the like releasably connected by a clamp or the like to the water hose. The adapter has a rear tubular stem portion inserted in one end of the hose and connected to a front expended spray head portion defining a plurality of water spray orifices. The front head portion can be cylindrical, spherical or anotehr shape and the orifices can be round, elongated, curved, etc. The exterior of the rear stem portion of the adapter may be convoluted, stepped, etc., to facilitate anchoring in the water hose. A water pulsator can be connected to the rear end of the adapter to cause water passing through the adapter to pulse outer the orifices for improved cleaning. The method includes drilling a hole through a brake backing plate, then passing the rear stem portion of the adapter out therethrough and connecting to the water hose, while leaving the spray front head portion within the drum cavity. Water is then passed through the hose and adapter so as to spray out of the adapter head into the drum interior in order to clean it and remove salt water, salt deposits, dirt, grime, etc., for improved functioning and corrosion resistance.
