  Hi John340, The colour of the brushes will be dictated by the manufacture - the generic brush may be one colour whilst the genuine part might be another. Where possible I would always recommend buying the genuine spare part for your appliance. You can find out if they're the right carbon brushes for your machine by locating your machine model number in our 'models this part fits' section on each page. For assistance finding your model number please see our guide: http://www.espares.co.uk/findingmodelnumbers.aspx#a7

• Colour makes no difference, as long as the brushes are the correct ones. Some motors are hard on brushes, hence the need to change them so often. Normally the brushes are the same colour as those originally fitted, but as I said it makes no difference if they are the correct set. It might be that the black set have a softer carbon insert than the white ones, but no problem in trying a white set and see if they last longer. Make sure that the white set are the correct set however for your machine. By donJ - Central Scotland - 23 November 2009
• might be fitted with inferior cheap chinese brushes in the past. check stator on motor for smoothness/no ridges that would wear brushes down. also check electrial spade connectors for overheating as will cause insufficient power to brushes and cause arcing/diminshe brush life. typically the plastic surrounding them goes brittle when overheated and spade goes black. ensure good clean connection on both brushes. grease bearings slightly with spray lithium grease (halfords next to WD40) prolong bearing life and ease load on brushes By derek645 - portsmouth - 01 November 2009
