Brake resevoir cover. 08/27/2011 ByDouglas Novotny Wow best of all the items I purchased> Actually made of metal. Installed with new resevoir and chrome cover. Looks Great. Only issue was that it caused a leak around the diaphram gasket. The diaphrram gasket in my case ended up being too thin and the seal was affected. Altered old diaphram and added it to the new one to stop the leak. Works fine and as previously stated Looks Great.
